Abstract
The present invention provides a digital signal waveform shaping circuit for reproducing a digital signal recorded on a recording medium. The waveform shaping circuit includes at least one comparator for receiving an input signal and a delay circuit connected to the output of the comparator for delaying the comparator output by one-bit-cell. The input signal is compared with a threshold level associated with the output of the delay circuit.
