ABSTRACT:
A synchronizing circuit for an oscilloscope or the like, in which in the case where a sync input signal contains composite periods like a PCM signal or video signal, it is identified to generate a sync pulse. The change-over operation of variable time-constant range of the sync identification circuit is electronically automated to meet a wide range or period. Also, automatic sweep time change-over becomes possible by interlocking the sweep circuit time-constant switch to the output data.
