Slicing ratio controlling circuit
First Claim
1. 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, comprisingdifferentiating 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.

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.
