Response:

Given circuit diagram:

First we consider the above op-amp circuit individually as below:

This circuit is a op-amp high-pass circuit and this acts as differentiator.

That is output is differentiation of input voltage.

...................... (1)

Consider first below op-amp of the given circuit individually

This is a inverting op-amp with a gain of

Therefore

...................... (2)

Consider second below op-amp of the given circuit individually

This is a inverting summing amplifier.

......................... (3)

From equation (1) and (2), we can modify equation (3) as below:

Given that

Now above equation becomes

Where

and

I hope this helps you...............
