In class we learned on replacing either output resistance or the input resistance in an inverting op amp which will give us an integrator or a differentiator.
A problem we did about replacing output resistor to create an integrator:
Another example, which we calculate a practical integrator:
We also were taught of singularity, and the 3 different functions of unit step, unit ramp, and unit impulse function.
unit step function (u(t)) is the derivative of unit ramp (r(t)), and the derivative of step function is the unit impulse function( sigma(t)).
An example that we did in class with regards to these functions:
