Abstract
A data slicing device includes an A/D converter for converting a video signal applied thereto into an equivalent digital signal, a sequential integrating circuit for averaging the amplitude of a dc component included in the digital signal obtained by the A/D converter, and a comparator for comparing a value of the digital signal obtained by the A/D converter with the average of the amplitude of the dc component obtained by the sequential integrating circuit so as to extract data from the digital signal.
