Abstract

PURPOSE:To obtain a clock reproducer which makes no error in signal processing by sending a regenerated clock signal with a few phase errors to a discriminating circuit and that, low in occurrence frequencies of cycle skips and false zero crossings, to a signal processing circuit. CONSTITUTION:Clock signal frequency component b extracted from received signal a by clock extractor 8 is branched by branching circuit 9. Signal component b1, on the other hand, has its unneeded component removed by the 1st tank circuit 10 and limiter circuit 11 band-limits it to obtain the 1st regenerated clock signal d1, which is sent to discriminating circuit 12. Selectivity Q of tank circuit 10 is so set that a phase error will be minimized, and the discriminating process of circuit 12 is performed excellently. Signal component b2 is passed through tank circuit 13 and limiter circuit 14 to extract regenerated clock signal d2, which is sent to signal processing circuit 15. Selectivity Q of circuit 13 is so set that the occurence frequencies of cycle skips and false zero-corrosings will be minimized. The signal processing of circuit 15, therefore, causes no error.
