Composite 240p Performance

For composite decoding this set uses a Philips TDA9377PS, a digital comb filter. It is excellent for 240p content, being equal or nearly equal in performance to a RetroTink's notch filter. All dithering patterns are blended properly, and fringing and dot artifacting are minimized or nonexistent.
