ABSTRACT: An FM transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Frequency modulation (FM) transmitter generates the radio waves by varying the radio signal's frequency slightly. FM transmitter is basically a VHF colipits oscillator capable of tr...
