Non ideality in output square wave of a differentiator circuit
rstofer:
https://www.3blue1brown.com/ is one of my favorite sites. I have spent may hours hanging out around there as well as at Khan Academy and CalcWorkshop (fee).

Practcally, I think the circuit will be limited by the slew rate of the UA741 which is about 0.5V/us. I would sure want to know more about the component values because I have problems when the simulation output is in terms of nanovolts.

The 741 opamp is 52 years old. Bury it and let it RIP.

Except that both of my Comdyna 6 Analog Computers are loaded with 741s and replacements are expensive. I'm somewhat reluctant to substitute but at some point that may just be the way it works out.
