Analog FM Transmitter
- Apr 02, 2018 -

Analog FM Transmitter: can only receive analog audio signals, audio signal amplification, limit and stereo coding are analog, especially the use of VCO (voltage control oscillator) +PLL (phase-locked loop) to generate FM carrier signal, modulation of course is also the use of analog composite audio signal to the VCO variable capacitance diode direct modulation.

This circuit is a typical analog FM transmitter, but may have led or LCD digital display transmitter operating frequency, but the whole process is simulated.
