Waveform equalizer for signal reproduced from a magnetic recording medium |
摘要 |
In a waveform equalizer of the present invention, first and second Hilbert-transform signals are formed from a parallel-reproduced signal, and a desired signal is obtained from these signals by an operational amplifier. The waveform equalizer includes a reflecting section having a plurality of resistors, and a switching section for selecting one of the resistors in accordance with a control signal. Therefore, the waveform equalizer can process a plurality of reproduced signals which have different ratios of the longitudinal signal component to the perpendicular signal component without being affected by inphase noise.
