ABSTRACT:
A synchronizing circuit for reproducing a synchronizing carrier wave from a received N-phase (N=2.sup.n, n being a positive real integer where n .gtoreq.1) PSK modulated carrier wave and employing a code converter circuit for adjusting the phase states of the received modulated carrier after demodulation thereof in order to enable the modulator to generate signals of the proper phase relation relative to an output carrier wave of a voltage controlled oscillator, which phase relationship is detected by a phase detector.
The code converter may be a logic gating circuit having control inputs for changing the output levels or a plurality of branching circuit pairs for each input each pair having a true and complement branch, and switch means for selectively coupling one of the branches to an output associated with each pair of branch circuits.
