Data slicer

Abstract

In determining a level of a digital signal to be either “0” or “1” (0/1-determination), erroneous determination occurring under influences of a noise superimposed on an input signal is prevented. A data slicer (100) receives a video signal digitized by an A/D converter circuit (1), as an input signal. A 0/1-determining circuit (2) determines a level of the input signal relative to a predetermined reference level, and outputs a digital signal (A) based on a result of the determination. A control part (3) outputs a control signal (B) based on the digital signal (A). The predetermined reference level used in the 0/1-determination is switched between two levels by a first selector circuit (4), based on the control signal (B).
