Abstract
In a waveform reshaping circuit for a digital signal which has become distorted, the threshold level is varied according to the codes of bits preceding each bit in a bit string forming data in the digital signal so that, even if coding interference takes place, a reshaped, undistorted digital signal outputted by the circuit is substantially the same in waveform as the original digital signal.
