Hi,
I am running an experiment that requires an ultrasonic pulse (cleaned up with a mono stable multivibrator) to be triggered on the positive slope of an optical chopper’s (used to modulate a laser beam) TTL square wave signal. I have the triggering down, but I need to shift the TTL signal’s phase to offset my ultrasound pulse with my laser pulse. The TTL runs at frequencies between 0-3000 Hz at a 50% duty cycle.
Does anyone have a simple solution to achieve this phase shift? Could this be done with passive components, or perhaps an op amp or NAND Gate?
Thanks,
Dan
