ABSTRACT:
Low-frequency components of a reproduced modulated signal is attenuated by an analog high-pass filter. The modulated signal with its low-frequency components attenuated is converted into a digital signal by means of an A/D converter. Then, the digital signal is directly introduced to a finite impulse response digital filter to be subjected to reproduced waveform equalization. Thereafter, the attenuation of the low-frequency components effected by the analog high-pass filter is compensated in an infinite impulse response digital filter.
