The FM transmitter, also called an "FM modulator," transmits the audio as an FM radio signal that is picked up by the car's antenna, while the cassette adapter uses a modified tape cassette.

It uses SDR techniques and a combination of AM and FM to achieve polar modulation and generate SSB. He’s provided a fascinating in-depth technical explanation to help understand how it works.

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel: 1. Technique of modifying any one characteristic (amplitude, frequency, or phase) of a ...
