Function IF input Standard switch: open B/G ground L Ground IF-AGC storage capacitor AGC (tuner control) Tuner AGC take over Polarity switch: open AFC “DOWN” ground AFC
Features
- D Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of the output signal
D High input sensitivity 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 flyback.
