Q: What is a 3D Y/C Digital Comb Filter?

A: The cable you plug into the back of your TV contains all the necessary parts of your favorite shows. But, the sound, the color information and the brightness information are all jumbled together. In order for a TV to use this mess, it has to separate everything out. This is the comb filter's job, and a 3D Y/C comb filter is the best. If your TV does not have a good comb filter, then the edges of objects can become rough and start to move. This effect is called dot crawl. A good comb filter will also lessen the effects of something called moiré. Moiré happens when a finely textured pattern seems to move and ripple when it shouldn't be moving at all. This is easily seen when a television newscaster wears a herringbone jacket.
