Comb filters any good for gaming?

[Ed Oscuro]

I understand these things work by adding a delayed version of the video signal to itself to create interference, and so lag is born. What I can't find are any specifications on the amount of lag comb filters add to the signal (especially for video), and whether it's remotely acceptable for gaming. I'm not really considering buying one (unless there's one both really cheap and really quick on single-plug composite signals), just curious.

Comb filters are great, lots of CRT TVs have 'em. The delay is about 3 lines max.

The necessary delay for implementing an NTSC or PAL comb filter is on the order of microseconds; even a 3-line delay like viletim mentions is only about a couple hundred microseconds. You probably get more delay from mechanical effects in your controller (notwithstanding the fact that most games only update the controller once per frame anyway).

That jives with what I saw elsewhere, though I only could find information for audio signals.

Yeah, you can make killer basses with a comb filter!

Nice. So, anybody got a recommendation for one to plug into a TV (say S-Video)? Finding a set that has one built-in seems out.

One of the or the best external comb filter for Composite to S-Video is the Entech SVSI-1 (marketed by Monstercable). Rather hard to find and not worth the effort for videogame signals (imo).
