C IN
S-LOW PASS SW
The chroma signal input pin.
Apply composite signal through
0.01 F of coupling capacitor.
The standard input signal level is
1 Vp-p.
The bell monitor switch for testing
is overlaid on this pin. When this
pin is connected to GND through
27 k, the bell filter output is
observed on Pin 7 (Y-OUT).

BELL f0-ADJ. FILTER
The pin for connecting the filter
capacitor for the bell filter f0,
4.286 MHz.
Too large a capacitor causes a
time delay on the bell filter f0
adjustment. Yet too small a
capacitor causes the picture to
be noisy.
