15.9 Video Section—Peak White Clip
The MC44BS373CA requires the following for proper video functionality:
This signal is AC-coupled to the video input where the sync tip level is clamped.
The video signal is then passed to a peak white clip (PWC) circuit. The PWC circuit function soft-clips the
top of the video waveform, if the sync tip amplitude to peak white clip goes too high. This avoids carrier
over-modulation by the video. Clipping can be disabled by software.

easily tune to the modulator output. The pattern consists of two white vertical bars on a black background
and a 976-Hz audio test signal.
