ABSTRACT:
The invention particularly relates to a system for demodulation of PSK signals which takes advantage from the effects that the locking of resonant circuits by superharmonic injection produce, together with the interference phenomena, and more particularly it relates to a demodulation system which is designed to avoid mutual locking between said resonant circuits.
