The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation FM transfers the information by varying the frequency of the carrier wave according to the message signal. This transmitter accomplishes the most excellent range with less power.

A short range FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device such as an MP3 player to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any nearby radio. This allows portable audio devices to make use of the louder or better sound quality of a home audio system or car stereo without requiring a wired connection. Being low-powered, most transmitters typically have a short range of — feet 30— meters , depending on the quality of the receiver, obstructions and elevation. Typically they broadcast on any FM frequency from In this project we design the circuit in such a way that ,the circuit will collect the input through aux cable and broadcast with in FM frequency range.

How To Build An FM transmitter Circuit Its Working and Applications

Limiter A limiter is a circuit whose output is constant for all input amplitudes above a threshold Limiters function in an FM receiver is to remove unwanted amplitude variations of the FM signal. Limiting and sensitivity A limiter needs about 1V of signal, called quieting or threshold voltage, to begin limiting When enough signal arrives at the receiver to start limiting action, the set quiets, i. RF signal to produce a specified level of quieting. Sensitivity example An FM receiver provides a voltage gain of , dB prior to its limiter. The limiters quieting voltage is mV. What is the receivers sensitivity? What we need is a device that linearly follows inst.

A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device such as an MP3 player to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any nearby radio. This allows portable audio devices to make use of the louder or better sound quality of a home audio system or car stereo without requiring a wired connection. They are often used in cars [1] but may also be in fixed locations such as broadcasting from a computer sound card throughout a building. Being low-powered, most transmitters typically have a short range of — feet 30— metres , depending on the quality of the receiver, obstructions and elevation.
