Abstract

An information processing apparatus in which an eye center measuring unit determines a code judgment point from a peak timing signal supplied from a timing signal generation circuit and an amplitude signal supplied from an interpolator and detected by an amplitude detector, and outputs it to a multiplier via an amplifier, a subtracter, and a reciprocal generating unit. A zero cross point measuring unit determines a code change point from a zero cross timing signal supplied from a timing signal generation circuit and an amplitude signal supplied from the interpolator and detected by the amplitude detector, and outputs it to the multiplier via a subtracter. The multiplier multiplies the supplied signals, and a dB converter converts a supplied signal into a signal in decibels and outputs the signal to a display circuit.
