I have the following picture of the input and output voltage waveforms from a differentiating amplifier as shown below:
And the schematic is as shown below:
My teacher claimed that these waveforms are correct, but I am starting to feel some doubt.
I calculated the equation of the line for input voltage waveform from time t=0 ms to t = 0.5 ms (with respective voltages of -500 mV and 500 mV) to obtain: y= 2000x - 0.5, and thus the output voltage waveform should be at y=2 mV for t=0 ms to t=0.5 ms, which is not shown in this picture.
Is this something to do with errors, or simply a mistake?
Also, I am aware that when differentiating a triangular waveform the output waveform should be square. So again, is the obtained picture a result of error (eg. from inaccuracies), or "human" mistake?
