Abstract :
F. M. Stereo Multiplex Demodulation is typically performed by (1) product detection and matrixing, or (2) square wave switching. In either case great emphasis has been placed upon utilizing a symmetrical waveform; that is, a non-distorted cosine wave in case (1), and a square wave with 50% duty cycle in case (2).
