Abstract
A slice circuit includes a DC component adjusting circuit, an integrator, a low pass filter, and a comparator. The DC component adjusting circuit adjusts only a DC component in an input signal sent from an input terminal to produce a DC component having a uniform voltage level. The integrator amplifies only a high frequency component of or above a predetermined frequency in the input signal received from the DC component adjusting circuit. The low pass filter detects an average voltage of the input signal received from the DC component adjusting circuit. The comparator compares a voltage of the output signal sent from the integrator with a voltage of an output signal sent from the low pass filter, and provides a digital signal having a logical level corresponding to results of the comparison to an output terminal.
