Yes another use of op amps!
Oscilloscope is the ZOYI ZT-702S

I'm still immersed in the Analogue world. What frequency input were you using? The sawtooth looks like a capacitor charge/discharge but there should be a constant current through the capacitor resulting in a linear voltage change (I think) as long as we don't approach the limits of the components. I wonder if the other capacitors on the board had any effect? Happy to be corrected here.
What would we see if a sawtooth waveform was input to the integrator and a sqare wave were input to the differetiator? How about a sine wave? Hopefully within the next year I will have a scope and can ask these questions myself. Thanks Bill
Lets see an opamp made from valves 😅
is it possible to make op amp integrator circuits that don't cause phase shift?
Integrating a sinewave by definition gives a cosine wave which is always lagging the input by 90 degrees.
Adding or subtracting time delays won't work because a 90deg phase shift implies a time delay that increases as the frequency decreases
that makes sense, i was wondering how the fixed rc timebase effects frequency response @@h7qvi
