Master timing generator

摘要: A master timing generator capable of tracking an externally generated clock signal and maintaining desired operation during periods disruption or perturbation the by noise other high-energy disturbances. The includes a voltage controlled oscillator input dc control to produce output which is maintained in particular phase relationship with lock loop circuitry coupled oscillator. standby representative value applied retained unit which, absence affecting signal, electrically uncoupled from When affected noise, alarm this condition causes be disengaged switched This employed its for so long as generator. Upon termination returns normal mode operation.
