source. (Can not be used as
external bias for Pins other
than 4, 6, and 9.)
Outputs chroma signal that
has passed through PB C
BPF and chroma feedback
comb filter subtracter
after frequency conversion
during playback.
Connects decoupling
capacitor for limiter of the
playback Y comb block.
Outputs Y signal processed by
comb filter. During playback,
the signal is output through
the sharpness circuit. If mode
E is set High, the signal is
output without passing
through the f sc Trap; if mode
SHP THRU is set High, the
signal is output without
passing through the sharp
-ness circuit.
VCA gain adjustment in the
comb filter block. (Refer to
Adjustment Procedure.)
