Features
- D Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of the output signal
D Fast AGC by controlled discharge of the AGC
capacitor
D Ultra white inverter and ultrablack limiter for
reducing transmission interference
D Standard L mode: AGC acting on peak white level,
capacitor discharge control by averaged video signal Standard B/G: AGC acting on the sync. pulse peak
D Internally noise protected gain control, no flyback
pulses required
D Expa.
