Abstract:
FM transmitter project allows transmission of signal from base station to receiver station. It can transmit our voice signal without any noise (disturbances). In this project the FM transmitter consists of different modules like modulator and power amplifier which generates an efficient amplified signal for transmission. The amplified signal is fed in to free space with an antenna. Here we use an aerial antenna for short range purpose. It is made from discrete bipolar junction transistors and induction coil. Continuous tuning is achieved with a variable capacitor. The designed tuning range was 88MHz to 108MHz. Its transmissions could be picked up on any common FM radio. The transmitter can transmit any types of audio like music in a 96 to 105MHz and it possesses a range of 500 meter.It is easy to communicate.
In economic view, it is better.
