Complex Numbers Freemat
In this activity we learned how to use Freemat to easily calculate complex solutions.
Integrating and Differentiating Op Amps
We observed the effects of integrating and differentiating op amps
This integrating op amp shows the yellow sinusoidal output with smaller amplitude to the integration effect of the op amp.
At this point the op amp was becoming saturated.
This differentiating op amp created a phase shift and decrease in amplitude in yellow.

In each case the frequency was maintained despite the operations, which is expected of AC circuits.
