I am making note of the IC1B operation when V2>V1.That's strictly an analog circuit, nothing digital about it.
Yes.
A diode can be used in an analog circuit (and is used in many of them) without making it digital.
Do you really think that any circuit with a diode is digital?
What else do you call a Analogue signal if it gets rectified into a ????? signal.
Or we could say what happens when a AC gets rectified ?????
