An input non-periodical signal starts when the circuit is powered on, BUT after some few milliseconds I want the output signal to be shifted in its phase at least 2PI (one full cycle), or have a sort of timer that outputs the signal a few milliseconds after.
How can I achieve this? Is there any type of a time-delay circuit with op-amps? I saw one but it only shifted the wave 180 degrees, it doesn't work for me, as I have analyze a full cycle first and then manipulate the shifted signal.
Something like this (e.g):
Signal [channel 1 to oscilloscope] -> Delay[500ms] -> The exact signal [channel 2 of osccilloscope], but starting 500ms after the circuit was powered on.
