ABSTRACT:
A jitter detection apparatus includes an A/D conversion section for converting an input analog signal into a plurality of discrete multiple value digital signals; a binarization section for performing binarization of the plurality of multiple value digital signals to generate a binary signal; a jitter calculation section for calculating a jitter amount based on an error between a value of a prescribed multiple value digital signal sampled at a time which is substantially the same as a time when the value of the binary signal is changed and a prescribed threshold value; a pattern detection section for detecting patterns of the binary signal before and after the time when the prescribed multiple value digital signal is sampled; and a correction section for correcting the jitter amount based on the detected pattern.
