Abstract
A signal decision circuit includes: a first decision circuit configured to identify a voltage level of an input signal using an average level of an amplitude of the input signal as a first threshold level; a detection circuit configured to detect an average of an amplitude absolute level based on the average level of the amplitude; a second decision circuit configured to identify a voltage level of the input signal using a second threshold level obtained by adding the average of the amplitude absolute level to the average level of the amplitude; and a third decision circuit configured to identify a voltage level of the input signal using a third threshold level obtained by subtracting the average of the amplitude absolute level from the average level of the amplitude.
