... AGC circuit The AGC circuit of the TDA8303/TDA8303A is a top-sync detector. The video signal coming from the video amplifier passes a 2nd order low-pass filter before it is compared with an internal reference level. The comparator stage is gated when the horizontal oscillator is synchronized with the video signal, such that interference pulses outside the gating time have no influence on the gain control ...
