Advanced Comb Filter-UH (AFC-11)

The Advanced Comb Hlter–11 is a video signal processor for VCRs and TVs.

It’s function is to separate the Luminance Y and Chrominance C signals from

the NTSC composite video signal. The ACF–11 minimizes dot–crawl and

cross–color. A built-in PLL provides a 4xfsc clock from either an NTSC

subcarrier signal or “a 4xfsc input. This allows a video signal input of an

extended frequency bandwidth. The built–in vertical enhancer circuit improves

the quality of the Luminance Y signal. The built–in ND and D/A converters allow

easy connection to analog video circuits.
