ABSTRACT:
A waveform equalizer, which has a partial response characteristic represented in the form of PR (a, b, c, b, a) which is a quaternary transfer function characteristic, is made up an analog filter, an ADC (analog/digital converter), and an FIR filter, for providing matching with the frequency characteristic of a read back waveform read from a recording medium. Such signal processor characteristic approximation to the regenerative signal characteristic makes it possible to easily achieve equalization without particularly emphasizing the regenerative signal, thereby achieving a reduced circuit scale.
