I was looking at a receiver catalog, and some of the receivers were
advertised as containing a "DSP comb filter" which could be turned on

Can anyone tell me what a comb filter does and when it would be used?

As others have mentioned, Comb Filtes are often used in video
applications.
This link dose a pretty good job of explaining what they are and why
they are used.
