to item 7 on Description of
Operation.)
Main emphasis and main de-
emphasis time constant.
When recording, the
emphasized Y signal prior to
white/dark clipping is output.
Main emphasis and main de-
emphasis time constant. Apply
an external constant between
this pin and Pin 2, as shown
below.
HPF time constant that forms
sub emphasis and sub de-
emphasis. Add resistance
between this pin and Pin 11.
During recording, Y emphasis
input. During playback, this
signal to the noise canceler is
input. Performs diode
clamping (sync tip clamping),
with the clamp capacitance
attached externally.
