Fm transmitter and future radio technology
ABSTRACT
FM Transmitter is a device which generates frequency modulated signal. It is
one element of a radio system which, with the aid of an antenna, propagates
an electromagnetic signal. Standard FM broadcasts are based in the 88 - 108
MHz range. Advancements have been made in the way FM is broadcast. This
includes utilizing such technologies as Hybrid Digital (HD) Radio, Software
Defined Radio (SDR) and Cognitive Radio.
HD Radio uses IBOC (In-Band On-Channel) as a methodof broadcasting digital
radio signals on the same FM channel, and at the same time as the
conventional analog signal while Software defined radio (SDR) is the term used
to describe radio technology where some or the entire wireless physical layer
functions are software defined.
Cognitive radio networks on the other hand, are intelligent networks that can
automatically sense the environment and adapt the communication
parameters accordingly. These types of networks have applications in dynamic
spectrum access, co-existence of different wireless networks, interference
management, etc.
Chapter4frequencymodulation 120317021055-phpapp01
Frequency modulation (FM) varies the frequency of the carrier signal based on the modulating signal. FM has better fidelity and noise immunity than amplitude modulation (AM). It uses constant carrier amplitude, requiring less complex circuitry than AM. However, FM uses more spectrum space than AM. A modulated FM signal has constant amplitude but varying frequency. Its instantaneous frequency and phase deviation are proportional to the modulating signal. The modulation index indicates the ratio of frequency deviation to modulating frequency. Bessel functions describe the spectrum of an FM signal and relative amplitudes of its carrier and sidebands.
Television Signal Transmission & Propagation
The document discusses various topics related to television signal transmission and propagation:
1) It describes the processes of picture signal transmission using amplitude modulation and the generation of a continuous sine wave at the carrier frequency.
2) It explains the differences between positive and negative modulation and their effects on picture quality, synchronization, and transmitter power output.
3) It discusses vestigial sideband transmission, which transmits only part of the lower sideband to reduce the required channel bandwidth from 11 MHz to 7 MHz.
4) It provides an overview of television signal propagation through ground waves, sky waves, and space waves and the factors that determine transmission range.

Fm transmitter and receivers
FM transmitters and receivers are used for sending and receiving FM signals. Transmitters modulate a carrier wave with an audio signal to generate an FM signal, which is transmitted through a band. Receivers receive the modulated signal, demodulate it to extract the original audio signal. FM offers advantages over AM like noise reduction, improved fidelity, and more efficient power use, though it requires more complex circuits and a larger bandwidth. Applications of FM include radio broadcasting, mobile radio, TV sound, and cellular/satellite communication.

Fm
FM broadcasting provides high-fidelity sound over radio using frequency modulation. It transmits two audio channels for stereo sound. FM has better noise control and signal quality than AM as environmental factors only affect amplitude, not frequency. However, AM has a greater transmission range. Key advantages of FM include high-fidelity sound, noise reduction, and ability to transmit stereo audio. Its uses include radio broadcasting, magnetic tape storage, and sound synthesis.
Frequency modulation and its application
This document discusses frequency modulation (FM) including its definition, modulation index, spectrum characteristics, types of FM modulation, generation of FM using phase modulation, advantages and disadvantages compared to other modulation techniques, and applications of FM such as in radio broadcasting, television sound, and satellite television. FM provides noise immunity and allows adjusting the noise level by changing the frequency deviation. It is widely used for radio but requires more complex transmission and reception equipment than other modulation methods.
Analog communication
This document provides an overview of communication basics and amplitude modulation. It discusses how communication involves transmitting and receiving information, and how modulation translates signals to higher frequencies for long-distance transmission. It then describes various amplitude modulation techniques like AM, DSB, and SSB. Key aspects covered include the AM envelope, frequency spectrum of AM waves, AM modulation indexes, and different AM modulation and demodulation methods.
Amplitude modulation
This PowerPoint presentation discusses amplitude modulation (AM). It defines AM as a process where the amplitude of a carrier signal is altered according to information in a message signal. Common applications of AM include broadcasting and aircraft communications. The presentation explains key aspects of AM signals such as the carrier signal, modulating signal, envelope, and modulation index. It also covers bandwidth, power measurements, and advantages of AM such as reducing antenna height and increasing communication range.

Robotic hand
The document discusses building a robotic hand that emulates the human hand. Students first draw and label a diagram of the human hand, then build an articulated finger model using a straw to understand finger bone anatomy and muscle movement. They create a flex sensor from everyday materials and add it to the articulated finger model to create a robotic finger. Students then connect the robotic finger and sensor to an Arduino Uno board to visualize finger flexion and extension data in Excel. Finally, students incorporate what they learned to build a complete robotic hand that can be controlled.
HOW IT WORKS

It also covers Ohm's law, Kirchhoff's laws, Thévenin's and Norton's theorems, binary number systems, logic gates, Karnaugh maps, and operational amplifiers. The document aims to explain the construction and working principles of basic electronic components for those new to the field of electronics.
Nano Biomaterials
This document discusses nanomaterials and their applications in tissue regeneration and drug delivery. It begins by classifying nanomaterials into 0D, 1D, 2D and 3D structures. It then describes how polymer scaffolds can be used to deliver growth factors to promote tissue regeneration, with factors either mixed into the polymer or encapsulated in microspheres. The document outlines different classes of degradable materials used for medical applications and lists properties of selected degradable polymers. It concludes by mentioning targeted drug delivery systems and providing references for further information.
Presentation on History of Microcontroller(Updated - 2)
The document provides a history of microcontrollers beginning with the development of the first microprocessor by Intel in the early 1970s. It then discusses how Texas Instruments engineer Gary Boone developed the first single-chip microcontroller called the TMS1802NC in the early 1970s. The document outlines some of the key developments in microcontrollers over subsequent decades, including Intel's 8048 and 8051 microcontrollers, the introduction of EEPROM and flash memory technologies, and modern microcontrollers used in various applications today.
Basics of Meditation
- The document introduces Alpesh Maru, a student studying biomedical engineering and neuroscience who is interested in meditation.
- Meditation is a process of gaining energy, power, and immunity and building a better lifestyle, as exemplified by respected figures like Buddha and Swami Vivekananda.
- It is better to practice meditation regularly, even if just for a short time each day. Morning and evening are generally good times, and it is best to meditate facing east or north for energetic benefits.
