Comb Filter Input
The inputs to the comb filter are selected from either the high
frequency outputs of the bandsplit filters, if using a chroma
comb filter, or the full composite waveforms when imple-
menting a luma comb. The two sets of high and low fre-
quency signals from the bandsplit filters are used for both the
luma and chroma
SIMPLE
signals, and in the generation of
the comb fail signals. These signals are denoted xHL, xHH,
and xHF where L denotes the low frequency portion of the
signal, H the high frequency portion of the signal and F the
full frequency spectrum of the input signal from line x; and
are shown in Figure 15.
