A device for the synchronization of a relaxation oscillator

摘要

Circuit arrangement for synchronizing an oscillator relaxation, in particular the oscillator to produce the control voltage for the vertical deflection circuit in a television receiver, by means of pulses square synchronization are supplied to a phase detector which is also supplied signal derived comparison oscillator relaxation, being filtered output voltage of the phase detector in a filter network for a DC voltage, filter network is connected to an input terminal of the oscillator, characterized by the fact comprise a channel whose output is connected to an input terminal of the oscillator, and in which is included an integrating network to integrate the square pulse supplied to the input sync channel.
