Key Features
- D Interference suppression 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 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 Ultra white inverter and ultra black limiter for reducing transmission interference D Internally noise protected gain control, no flybac.
