From the project
Analog Composite Video to S-Video comb filter board using SAA4960, SAA4961 or SAA4963 integrated circuit
This is a fully analog alternative to digital comb filters such as Extron YCS Transcoder or YCS 100. That doesn't mean it will give better results though. I just made it because I didn't find any fully analog device like that on the market and I wanted one.
The comb filter is used to convert a composite video signal into an S-Video (Y/C) signal. Comb filters are much better than passive LC filters usually built into composite video displays, as they can preserve the frequencies of luminance that overlap with chrominance, providing higher image detail while removing dot crawl, and remove…
