In Telecommunications, Frequency Modulation (FM) conveys information everyplace a carrier wave by varying its frequency.



FM is commonly use at VHF radio frequencies for accurate broadcasts of music and speech. Throughout the world, the broadcast band falls at bottom the VHF part of the radio spectrum. Usually 87.5 108.0 megacycle is used to transmit and receive the FM signals. Designing and assembling an FM transmitter is a difficult task. The Note given hither explains how a simple FM transmitter is designed and assembled.



Design Considerations

The performance of an FM transmitter depends on two all- measurable(a) aspects.

1. Tuning of the FM transmitter to the desired frequency. Even a slight change in the coil specification or slight change in the variable capacitor take to be can shift the harmonic frequency instead of the 88-108 MHz FM band.
2. Length of the Antenna used to transmit the frequency.
