Differentiator circuit
Consider the effect of a low-pass filter on a rectangular shaped input pulse with a width
and period .
The first thing to consider is what happens to the different parts of the square pulse as it travels to the circuit.
You know that the circuit, as a high pass filter, will tend to attenuate low frequency (slow changing) voltages and not high frequency (quick changing) voltages.
This means that points a and b in the pulse shown below should pass through the
