Abstract
The data slicer circuit has a first capacitor that holds a pedestal potential of a video signal; a second capacitor that calculates an average potential of signals existing in a period where a clock run-in signal of the multiplex signal is present and holds the average potential; and a comparator which compares the two held potentials. The comparator outputs a detection signal indicative of the presence of the multiplex signal when the potential held by the second capacitor is higher than that held by the first capacitor.
