Title: Clock extract circuit
Inventor: SUZUKI MITSUHIRO
IPC: H04L27/22
Filed: 1992-05-29
Abstract: PURPOSE:To extract a clock signal of a signal modulated in phase modulation with high accuracy and simple configuration by obtaining a difference at a mod2pi between a phase detection signal this time and a preceding phase detection signal. CONSTITUTION:Phase information fed from a phase detection circuit to a phase information input terminal 21 is fed to D flip-flop circuits 23, 24 connected in 2-stage. In this case, a timing signal whose frequency is four times that of the symbol clock obtained at a timing signal input terminal 22 is fed to a clock input terminal of the D flip-flop circuits 23, 24. An output of the D flip-flop 24 delayed by 1/2 clock is subtracted from an output of the D flip-flop circuit 23 delayed by 1/4 clock by a subtractor 24. In this case, subtraction processing obtaining the difference of mod2pi is implemented. Then the subtraction output of the subtractor 25 is fed to an absolute value detection circuit 26. Then the processing to detect the absolute value of the subtraction output is implemented by the absolute value detection circuit 26 and the clock component is extracted.
