Abstract

PURPOSE:To prevent the disappearance of a timing signal due to the increase in the distortion of an input signal, by picking up the same clock component from different frequency components. CONSTITUTION:The output of nonlinear circuits 3, 4 in which the same block component is picked up from different frequency components is added at an addition circuit 5 to obtain a timing signal via a narrow band pass filter 6.
