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
and in the pulse shown below should pass through the circuit while the DC level parts would not.
