ABSTRACT:
A slicing ratio controlling circuit for controlling the ratio of a slice level used when binarizing an input signal with respect to the signal to be sliced, including a differentiating unit for differentiating the input signal; a peak holding unit for receiving the differentiated signal from the differentiating unit and holding its peak level so as to generate a slice level signal; and a constant ratio enabling unit for making the ratio of the slice level signal from the peak holding unit with respect to the differentiated signal constituting the signal to be sliced a constant ratio regardless of the magnitude of the differentiated signal.
