Page 14 All manuals and user guides at all-guides.com DIGITAL COMB FILTER – TOSHIBA TC9090AF. The operation of a comb filter is to separate the composite video into luminance and reconstruct the chrominance colour sub carrier signal using digital signal processing techniques. The comb filter IC, IN01 has an additional vertical edge enhancement feature. Composite video input (Pin 6 of connector E500) and colour sub-carrier (pin 8 of E500) are converted via an 8 bit analogue to digital converter where the vertical enhancement and digital comb filtering takes place.

Page 161 All manuals and user guides at all-guides.com Der integrierte Schaltkreis enthält einen automatischen farbbegrenzenden Schaltkreis, der schaltbar ist, was Übersättigung verhindert, wenn Signale mit einem hohen Chrominanz-zu-Farbsynchronsignal-Verhältnis empfangen werden. Der acl Schaltkreis ist so konzipiert, dass er nur das Chrominanzsignal vermindert und nicht das Farbsynchronsignal. Dies bietet den Vorteil, dass die Farbempfindlichkeit nicht von dieser Funktion betroffen wird.
