QUANTIZATION ERROR AND NOISE
This document discusses pulse code modulation (PCM) and quantization noise. It explains that quantizing an analog signal introduces quantization error or noise. The quantization noise is modeled as a random variable with a uniform probability distribution between +/- step size/2. The step size depends on the number of quantization levels. A higher number of quantization levels reduces the step size and quantization noise, increasing the signal-to-noise ratio. The document also discusses different types of quantizers like uniform, midtread and midrise quantizers.
Digital Communication Techniques
This document discusses source coding and channel coding in communication systems. It defines source coding as the process of encoding source data, such as speech or text, into binary format before transmission. Channel coding adds redundancy to encoded data to detect and correct errors during transmission over a noisy communication channel. Common source coding techniques discussed include Huffman coding and Lempel-Ziv algorithms, while channel coding includes block codes and convolution codes. Entropy, mutual information, and other information theory concepts are also introduced.
Pulse code modulation
PCM is an important method of analog-to-digital conversion where an analog signal is converted into an electrical waveform of two or more levels. The essential operations in a PCM transmitter are sampling, quantizing, and coding the analog signal. In the receiver, the operations are regeneration, decoding, and demodulation of the quantized samples. Regenerative repeaters are used to reconstruct the transmitted sequence of coded pulses and perform equalization, timing, and decision making functions. While PCM systems allow for regeneration and multiplexing, they are more complex than analog methods and increase channel bandwidth requirements.

Manchester coding
Manchester encoding is a line code technique where each bit is represented by transitions at the midpoint between bit periods, with a '1' represented by a high-to-low transition and a '0' represented by a low-to-high transition. This allows the clock to be recovered from the encoded data and makes synchronization easier. While it requires double the bandwidth of other coding schemes and relies on correct polarity detection, Manchester encoding has found wide use for radio transmission of digital data.

Baseband Digital Data Transmission
Digital transmission systems transmit data in a baseband (low frequency) signal over a channel like a telephone line or cable. To allow transmission over bandwidth-limited channels, the transmitter filters the infinite bandwidth digital signal to limit its bandwidth before sending it over the channel. The receiver then filters the received signal and samples it to make decisions on the transmitted bit values, in order to minimize bit errors caused by noise in the channel during transmission.

Then it covers various line coding techniques including unipolar, polar, bipolar, and Manchester coding. It discusses the properties, advantages, disadvantages and power spectral density of each technique. Finally, it provides a comparison of polar RZ, polar NRZ, AMI and Manchester coding in terms of their transmission of DC components, signaling rate, noise immunity, synchronization capability, bandwidth requirement, and crosstalk.
Digital modulation
Digital communication systems allow transmission of information in digital form from one point to another. They involve source encoding, channel encoding/modulation, transmission over the channel, and decoding/demodulation at the receiver. Key concepts include frequency, bandwidth, sampling, quantization, line coding, multiplexing, channel coding, and digital modulation techniques like PSK, FSK, ASK, and QAM. Multiple access methods like FDMA, TDMA, and CDMA are used to enable multiple users to access the channel simultaneously. Duplex systems can be simplex, half-duplex, or full-duplex depending on the direction of transmission.
Unipolar Encoding Techniques: NRZ & RZ
Unipolar encoding techniques such as Unipolar-NRZ and Unipolar-RZ are discussed. Unipolar encoding uses only one polarity of voltage level (0 and 1) to represent binary data. Unipolar-NRZ does not return to zero in the middle of a bit while Unipolar-RZ does return to zero, consuming twice the bandwidth of Unipolar-NRZ. Both techniques have advantages and disadvantages related to implementation complexity and error handling. Signal drooping can occur when low frequency components in unipolar signals cause distortion as they pass through AC coupled transmission lines.
Frequency-Shift Keying
Frequency-Shift Keying, also known as FSK is a type of digital frequency modulation. It is also often called as binary frequency shift keying or BFSK
Similar to analog FM, it is a constant-amplitude angle modulation.
This presentation will discuss the concepts behind FSK
Delta Modulation
Delta modulation is an analog-to-digital conversion technique used to transfer data. It works by comparing an input signal to a reference signal and encoding the difference into a digital bitstream. A delta modulation system consists of a modulator that converts an analog signal to digital, and a demodulator that converts the digital signal back to analog. Delta modulation is simpler than pulse code modulation but can achieve high signal-to-noise ratios and variable bandwidth. However, it is limited by slope overload when signals change rapidly.
Digital signal processing
Digital signal processing involves the analysis, interpretation, and manipulation of signals such as sound, images, and sensor data. It represents analog waveforms as discrete numeric values by sampling the waveform at regular intervals. There are two categories of signal processing: analog and digital. Digital signal processing has advantages over analog like greater noise immunity, multi-directional transmission, security, and smaller size. It has applications in areas like digital filtering, video and audio compression, speech processing, image processing, and radar/sonar processing.

Multiplexer & de multiplexer
This document discusses multiplexers and de-multiplexers. It defines a multiplexer as a circuit that accepts multiple input signals but provides a single output signal, selecting one input using control signals. A de-multiplexer is the opposite, accepting one input and providing multiple outputs. Examples of 4-to-1 multiplexers and 1-to-4 de-multiplexers are described. Applications include communication systems, computer memory, and transmitting satellite data. Multiplexers and de-multiplexers are commonly used together and are important combinational logic circuits.
BCH Codes
BCH codes, part of the cyclic codes, are very powerful error correcting codes widely used in the information coding techniques. This presentation explains these codes with an example.
Delta modulation
Delta modulation is a modulation technique that transmits only one bit per sample of an analog signal. It works by comparing the present sample value to the previous one and transmitting a bit to indicate if the value increased or decreased. This results in a stepped approximation of the original signal. Only a single bit is needed per sample, allowing delta modulation to have a lower signaling rate and bandwidth than PCM. However, it suffers from slope overload distortion if the input signal changes too quickly for the fixed step size. It also produces granular noise for small input variations due to the large step size. Despite these issues, delta modulation is used for voice transmission systems due to its simple implementation and emphasis on timely delivery over quality.
Telecommunication switching system
This document discusses simple telephone communication systems and their components. It describes how a carbon microphone works as an amplitude modulator to transmit sound signals along the line. An inductor allows DC current to flow while acting as a high impedance element for voice signals. At the receiver, an electromagnet converts the electrical signals back into sound waves. Early telephone systems used half duplex communication and included sidetone circuits to allow users to hear themselves. The document also covers the components and operation of local battery and central battery telephone exchanges.

- 4. What is Demultiplerxer ? A demultiplexer (or demux) is a device that takes a single input line and routes it to one of several digital output linesA demultiplexer is also called a data distributor. A demultiplexer has N control inputs 1 data input 2N outputs. A demultiplexer routes (or connects) the data input to the selected output. The value of the control inputs determines the output that is selected. The reverse of the digital demultiplexer is the digital multiplexer.
- 5. Applications of De-Multiplexer : De-multiplexer is used to connect a single source to multiple destinations. The main application area of de-multiplexer is communication system where multiplexer are used. • Communication System • ALU (Arithmetic Logic Unit) • Serial to parallel converter
