DESIGN AND CONSTRUCTION OF AN FM TRANSMITTER

ABSTRACT

This project work is on the construction of an F.M transmitter this system consists of four discrete modules namely the audio frequency (AF) amplifier (class A) the modulator the master oscillator and the radio frequency (RF) amplifier (ClassC) these formed the conventional events for building FM transmitter here the signal (from the microphone) is fed into the (AF) for amplification then to the modulator which combines the modulating signal with the carrier wave transports the modulated signal through (RF) for final amplification to the antenna via the resonance circuit for propagation the transmitter was tested using radio receiver it transmitted clearly at the frequency of 108 MH3 and the coverage was to metres.
