Abstract
A wave-shaping circuit for digital signal includes a slice or clipping circuit for slicing or clipping an input digital signal with a predetermined threshold level; a detecting circuit for detecting the pulse widths of high and low level portions of the sliced digital signal; and a control circuit which lowers the threshold level of the slice circuit, when the pulse width of the high level portion of the digital signal is short with respect to the normalized digital signal, and rises the threshold level of the slice circuit, when the pulse width of the low level portion of the digital signal is short with respect to the normalized digital signal.
