ABSTRACT:
There has been provided an improved switching circuit for an oscillographic apparatus wherein a determining wave form signal is compared with a reference level signal to provide a trigger control signal. The trigger control signal, a low level signal, is selectively gated to produce a signal in response, selectively, to the negative slope comparison or the positive slope comparison. The last-mentioned signal is then used to produce a trigger signal to trigger a sweep signal generator for the oscillographic apparatus.
