Abstract
A multiplexed signal receiver is arranged such that two independent signals are multiplexed on a single carrier by amplitude and frequency modulation or amplitude and or phase modulation. The multiplexed signal receiver includes a balanced type amplitude limiter and two double balanced type product detectors for amplitude and frequency or amplitude and phase demodulation. The receiver uses the direct coupling between said amplitude limiter and the two product detectors to facilitate the circuit integration thereof on a monolithic semiconductor chip.
