ABSTRACT:
A data slicer circuit is disclosed which comprises a control circuit to output a digital signal that increases or decreases by a constant value difference depending on the level of an input signal when the input signal is sampled at a given frequency; a conversion circuit to convert the digital signal to an analog signal; and a comparison circuit to compare the video signal with the analog signal, the comparison circuit outputting the result of the comparison as the input signal to the control circuit, wherein the analog signal corresponding to the result of the comparison of the comparison circuit is used as a slice level for separating the data from the video signal.
