SPECIAL TUBEBASE in general
|
| Descrizione |
-
High stability of the 4,4 MHz subcarrier oscillator against temperature and supply voltage variations
-
High noise immunity by triggering ACC and APC circuits
-
High noise immunity of the identification circuit
-
Internal generation of a combined blanking and burst key pulse by means of the flyback pulse
-
When the antenna signal decreases, chroma saturation is automatically reduced before colour killer action
-
Colour killer acts at low antenna signal, or oscillator not locked, or PAL-flipflop incorrectly identified, or no burst
-
The colour killer is working with a hysteresis
-
No adjustments of ACC level and gain are needed
-
Integrated 90° phase shifter
