Fm generation methods
WebOpen the simulation file. In the circuit, an FM signal with a 1kHz modulating frequency, 5V-20kHz carrier signal, and a modulating index of 5 is fed to the input. The tuned circuit formed by C 1 and L 1 performs the FM-to-AM conversion and the peak detector formed by D 1, R 2, and C 2 extract the information from the AM envelope. Run the ... WebFrequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing.. In analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous …
