ABSTRACT:
A partial response system useful in binary data communication systems is disclosed. The partial response system includes a transmission system adapted to provide an output having a frequency spectrum substantially input of pulse width T. A precode-converter is provided at the input side of the transmission system, and a waveform converter is inserted between the pre-code-converter and the transmission system. The frequency spectrum of the output of the waveform converter in response to a single pulse transmission system includes a waveform shaping filter having a transfer function represented substantially by either ##EQU1## Since the filter characteristic involves only an amplitude-characteristic, the design of the filter is greatly simplified.
