■ TEST CIRCUIT
■ OPERATIVE PRINCIPLE
- 4 -
● M. M
● LPF
● Comparator : Outputs discriminating signal of input signal by DC level of LPF output.
● Switch
: Makes exchanging operation of SYNC Input and SSG SYNC Input signal by discriminating signal
: Varies duty ratio of output signal depended on input synchronous signal condition (irregular, on, signal)
: Converts M. M. output signal to DC level. The more larger the duty ratio is,
DC level is clamped at V
Stabilized output signal can be obtained due to that the hysteresis is given to the output.
from comparator or Pin 6 signal of SYNC DET Output Judgement Control.
