ABSTRACT:
A subsample signal processing apparatus includes a wide-band D/A converter receiving a digital television signal which is compressed in band by subsampling. A signal processor subjects a video signal portion of an output signal from the D/A converter to wide-band processing. The signal processor subjects a sync signal portion of the output signal from the D/A converter to narrow-band processing. An output terminal of the signal processor and an input terminal of a subsequent A/D converter are coupled with wide-band coupling characteristics.
