Abstract: A digital finite impulse response (FIR) filter is provided in which a plurality of weighted signal taps are symmetrically located in time about a weighted center tap. Weighted signals from the symmetrically located taps are summed at a first point in the filter, which sum is then combined with signals from the center tap in one sense, that is, either additively or subtractively, to produce signals at a first output. The summed signals at the first point are also combined with signals from the center tap in an opposite sense to produce signals at a second output. The two outputs will exhibit bandpass and lowpass filter response characteristics, with the outputs at which the respective responses are produced being determined by the respective senses of signal combination. The FIR filter may be of either the input tap-weighted or output tap-weighted variety.

Abstract: A frame-to-frame comb filter for separating chrominance and luminance signals from composite video signals produces objectionable double images around the edges of moving objects. The double images are substantially removed by low pass filtering the combed chrominance signal and combining the low pass filtered chrominamce signal with the combed luminance signal.
