ABSTRACT:
In a PSK carrier regenerating circuit, a second regeneration path is provided for regenerating a carrier which is less susceptible to cycle slip phase errors. A variable phase shifter is provided at the output of the first carrier regeneration path to selectively shift the phase thereof in accordance with a phase comparison of the first and second regenerated carriers.
