Hi All,


What does Differentiator and Integrator circuits mean and how they are

mathematically related and for what for they are used!!!!!


Thanks

Circuit: RC filters. A differentiator is a high-pass, an integrator a low-pass
Math: Derivative/Integral
Application: Filtering out noise (int), acting on the steepness of a function (diff), ...

The output of an integrator is the integral with respect to time of the input.
The output of a differentiator is the derivastive with respect to time of the input.

These two circuits can be implemented in a variety of ways. They can be used to construct analog computers which can solve differential equations in continuous time. This is very different from the numerical solutions performed in discrete time on digital computers.
