Pulse amplitude modulation (PAM)
Pulse-amplitude modulation (PAM) encodes message information in the amplitude of signal pulses. A PAM-4 modulator takes two bits at a time and maps them to one of four amplitude levels, such as -3V, -1V, 1V, and 3V. Demodulation detects the amplitude level of each symbol period. PAM is widely used for baseband digital data transmission, though other modulation methods are now more common.
Pulse amplitude modulation
The document provides instructions for 14 experiments in analog communications lab, including voltage feedback amplifier, amplitude modulation and demodulation, class A power amplifier, RC phase shift oscillator, Hartley and Colpitts oscillators, complementary symmetry push-pull amplifier, DSBSC modulation and demodulation, SSBSC modulation and demodulation, frequency modulation and demodulation, pre-emphasis - de-emphasis circuits, verification of sampling theorem, PAM and reconstruction, PWM and PPM generation and reconstruction, and the effect of noise on communication channels. The experiments are designed to help students learn important concepts in analog signal processing and analog communications systems.
PAM
This document provides an overview of pulse amplitude modulation (PAM). It defines PAM as a modulation technique where the message information is encoded in the amplitude of a series of signal pulses. There are two types: single polarity PAM which adds a DC bias to ensure all pulses are positive, and double polarity PAM where pulses can be both positive and negative. PAM is used to modulate digital data transmission and involves sampling the message signal to vary the amplitude of a carrier pulse train. The modulated signal is then detected by measuring the amplitude level of each carrier pulse.
pulse modulation
This document summarizes various pulse modulation techniques including:
- Pulse-amplitude modulation (PAM) where the carrier amplitude changes with the message signal amplitude.
- Pulse-duration modulation (PDM) where the carrier width changes with the message signal amplitude.
- Pulse-position modulation (PPM) where the carrier position changes with the message signal amplitude.
- Digital pulse modulation techniques like pulse code modulation (PCM) and differential PCM (DPCM) are also discussed. Advantages and disadvantages of each technique are provided.
Pulse modulation
The chapter discusses various types of pulse modulation techniques including pulse amplitude modulation (PAM), pulse width modulation (PWM), pulse position modulation (PPM), and pulse code modulation (PCM). PAM varies the amplitude of pulses based on the analog signal, PWM varies the width of pulses, PPM varies the position of pulses, and PCM converts the analog signal to a digital code using sampling and quantization. Digital communication through pulse modulation offers advantages like easier reception, less signal corruption over distance, ability to clean up noise and amplify signals, security through coding, and ability to store signals.
Pulse modulation
Pulse modulation techniques can encode an analog signal for transmission. This document discusses several techniques including:
- Pulse-amplitude modulation (PAM) which varies pulse amplitudes based on sample values of the message signal.
- Pulse code modulation (PCM) which assigns a binary code to each analog sample. PCM is commonly used in digital communications systems.
- Delta modulation which transmits one bit per sample indicating if the current sample is more positive or negative than the previous. It requires higher sampling rates than PCM for equal quality.
Phase shift keying Presentation
Phase-shift keying (PSK) is a digital modulation technique that conveys data by changing the phase of a carrier signal. There are three major classes of digital modulation: amplitude-shift keying, frequency-shift keying, and phase-shift keying. Quadrature phase-shift keying (QPSK) is a type of PSK that can either double the data rate compared to binary phase-shift keying (BPSK) while maintaining bandwidth, or maintain the BPSK data rate while halving the required bandwidth. QPSK works by splitting the binary data stream into in-phase and quadrature-phase components at the transmitter, and using matched filters or correlates to detect symbols at the receiver.
Pulse code modulation
Pulse code modulation (PCM) is a digital representation of an analog signal where the signal is sampled regularly at discrete intervals and each sample is converted to a binary word. This allows analog signals like audio and video to be transmitted over digital networks or stored digitally. PCM works by sampling the analog signal, quantizing the sample amplitude to the nearest of several levels, and encoding each level as a binary number consisting of a certain number of bits depending on the number of quantization levels used.

Pulse width modulation (PWM)
Pulse width modulation (PWM) is a method of changing the duration of a pulse with respect to the analog input. The duty cycle of a square wave is modulated to encode a specific analog signal level. This pulse width modulation tutorial gives you the basic principle of generation of a PWM signal. The PWM signal is digital because at any given instant of time, the full DC supply is either ON or OFF completely. PWM method is commonly used for speed controlling of fans, motors, lights in varying intensities, pulse width modulation controller etc. These signals may also be used for approximate time-varying of analogue signals. Below you can see the pulse width modulation generator circuit diagram (pulse width modulator) using op amp. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion. Pulse width modulation dc motor control is one of the popular circuits in Robotics.
Digital communication
This document discusses baseband shaping for data transmission. It introduces several digital modulation formats used for discrete PAM signals like unipolar, polar, bipolar and Manchester encoding. It then discusses factors that affect transmission like DC component, bandwidth, bit synchronization and error detection. It describes intersymbol interference and its causes like multipath propagation and bandlimited channels. It presents the baseband binary data transmission system model. Nyquist's criterion for zero ISI is defined. Practical solutions like raised cosine filters are discussed. The transmission bandwidth requirement is derived based on the rolloff factor. Finally, it describes what an eye diagram reveals about the system performance.

Modern SATCOM Forward Error Correction
This document provides an overview of modern forward error correction (FEC) techniques used in satellite communications (SATCOM). It discusses the motivation for using FEC to combat various link impairments. It then reviews various FEC schemes including block codes, convolutional codes, turbo codes, and compares their performance. Turbo codes are shown to provide the best performance, approaching the theoretical Shannon limit, allowing for reduced transmitter power and bandwidth compared to older FEC schemes. The document concludes that while newer codes like turbo codes offer close to optimal performance, simpler block and convolutional codes also provide good performance for their lower complexity.
Radio receivers
This document discusses the history and types of radio receivers. It describes how the earliest radio receiver was created in 1896 by Alexander Popov and was based on Maxwell's discovery of electromagnetic waves. There are three main types of receivers discussed - crystal radios, tuned radio frequency receivers, and superheterodyne receivers. Crystal radios require no power source beyond the radio waves themselves, while tuned radio frequency receivers have individually tuned amplifier stages and superheterodyne receivers mix signals to extract an intermediate frequency. The document also covers frequency ranges, sensitivity, selectivity and how radio waves propagate.
Pulse amplitude modulation
This document discusses pulse amplitude modulation (PAM). PAM is a digital modulation technique where the amplitude of pulses is varied to represent data symbols. In PAM, each pulse amplitude corresponds to a data symbol value. The document discusses binary and M-ary PAM schemes. It also covers topics like intersymbol interference, eye diagrams, Nyquist pulse shaping criteria, and raised cosine pulse shaping to minimize intersymbol interference at the receiver. PAM is used to convert discrete amplitude symbols into analog pulses for transmission over a channel, and the receiver demodulates the signal to recover the data symbols.
Propagation mechanisms
There are 3 main propagation mechanisms in mobile communication systems:
1. Reflection occurs when signals bounce off surfaces like buildings and earth.
2. Diffraction is when signals bend around obstacles like hills and buildings.
3. Scattering is when signals are deflected in many directions by small obstacles like trees and signs. These 3 mechanisms impact the received power and must be considered in propagation models.
Amplitude shift keying
Amplitude shift keying (ASK) is a digital modulation technique that represents binary data by changing the amplitude of a carrier wave. In binary ASK (BASK), also known as on-off keying (OOK), a high amplitude represents a binary 1 and a low or off amplitude represents a binary 0. The demodulator determines the amplitude of the received signal to recover the original data. ASK transmitters and receivers have a simple design but the transmission is susceptible to noise. ASK is used in early telephone modems and transmitting digital data over optical fibers.
ADDITTIVE WHITE GAUSIAN NOIS ( AWGN)
1) The document discusses digital modulation techniques for transmitting digital information over an additive white Gaussian noise (AWGN) channel. It describes geometric representations of signal waveforms and orthogonalization procedures.
2) Binary and M-ary modulation schemes are covered, including binary antipodal signaling, orthogonal signaling, pulse position modulation, and frequency-shift keying. Optimal receivers for the AWGN channel using correlation and matched filtering are also described.
3) Probabilities of error are derived for various digital modulation techniques, including M-ary pulse amplitude modulation, phase-shift keying, and quadrature amplitude modulation. Differential phase-shift keying is also introduced.
Pulse modulation (pam)
Pulse amplitude modulation (PAM) is a method where the amplitude of pulses is varied proportionally to the message signal voltage. PAM uses flat-top sampling and the signal is easily affected by noise. It can be constructed in the time domain and frequency domain. Ideal sampling can eliminate noise but is difficult to generate, while detection of PAM samples requires the low-pass filter cutoff frequency to be between the message frequency and sampling frequency, plus a guard band.
Digital communication methods
ASK, FSK, PSK, and QAM are common digital modulation techniques. ASK represents binary digits by transmitting different amplitude carrier waves. FSK uses different frequencies, while PSK and QAM vary the phase and amplitude of the carrier signal. PSK can be binary BPSK or quadrature QPSK using four phases. QAM combines amplitude and phase modulation for increased data capacity.
Gaussian noise
The document discusses Gaussian noise, which refers to statistical noise that follows a normal distribution. It is commonly found in digital images, telecommunications systems, and other contexts. Some key points made in the document include:
- Gaussian noise arises from natural sources like thermal vibrations and has a probability density function given by the normal distribution.
- In digital images, it provides a good model for sensor and transmission noise and can be reduced using spatial filters, though this may also blur details.
- It is commonly used to model thermal noise in communication channels, where it is assumed to be additive, white, and have a Gaussian distribution.
- Bit error rate and packet error ratio are measures of noise that indicate the need
Mobile Radio Propagations
Mobile radio propagation models are derived using empirical and analytical methods to account for all known and unknown propagation factors. Signal strength must be strong enough for quality but not too strong to cause interference. Fading can disrupt signals and cause errors. Path loss models predict received signal level as a function of distance and are used to estimate signal-to-noise ratio. Path loss includes propagation, absorption, diffraction, and other losses. Large-scale models describe mean path loss over hundreds of meters while small-scale models characterize rapid fluctuations over small distances.

Use PyCharm for remote debugging of WSL on a Windo cf5c162d672e4e58b4dde5d797...
This document serves as a comprehensive step-by-step guide on how to effectively use PyCharm for remote debugging of the Windows Subsystem for Linux (WSL) on a local Windows machine. It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
