WAVEFORM EQUALIZATION COEFFICIENT ADJUSTING METHOD AND CIRCUIT, RECEIVER CIRCUIT, AND TRANSMISSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a waveform equalization coefficient adjusting technology to reduce an adjustment time of the waveform equalization coefficient.

SOLUTION: In a waveform equalization coefficient adjusting method, a jitter or an amplitude is measured only in the case of an optional signal sequence and the waveform equalization coefficient is adjusted. Particularly, a signal inverting time is measured by using a signal other than 010 or 101 signal among received signals. As the signal inverting time in the case of using the signal like this is very sharp compared with a conventional technology, the adjustment time of the waveform equalization coefficient is reduced.
