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.

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, comprising
- differentiating means for differentiating the input signal;
- holding means for receiving the differentiated signal from the differentiating means and holding a signal related to the peak level of the differentiated signal and generating a slice level signal as a function of said signal related to the peak level of the differentiated signal;
- and
- making means for making the ratio of the slice level signal of the holding means to the differentiated signal substantially constant for substantially all d.c. values of the differentiated signal.
