SCHALTUNG ZUR KOMPENSATION DES FREQUENZGANGABFALLES EINES SIGNALS

摘要

A circuit compensates the frequency response decline - caused by the D/A converter (4) - of a video signal supplied via A/D and D/A converters (2, 4) by means of a 1/si(x) equalizing circuit (1). The 1/si(x) equalizing circuit (1) is arranged upstream of the A/D converter (2), while the D/A converter (4) is operated at a variable clock frequency (fcv). <IMAGE>
