(Reference: go back and read my last posting about comb filters.)

Comb filters are a better way of seperating the B&W and color parts
of a video signal.  As for "dual" comb filters, I assume that there
is one comb filter to grab the B&W part of the image and another to
grab the color part.  Theoretically, you could choose to only use
a comb filter on one part or the other (probably the color part).
