Help to stregnthen laplace and second order diff eq beckground

[keith03]

Homework Statement

Here is my issue. I am an EE student that has been part time for almost five years. I took diff eq and signals a long time ago. I am currently taking a feedback and controls class, and my lack of memory in these topics is killing my study time. I am looking for relevant guidance or practice problems to stregnthen a foundation for:

Modeling Electromechanical Systems
Classical approach to feedback systems (not modern)


I need a refresher. Please let me know if more info is necessary. I know that when the light pops on again, it will be one of those "dumb" moments' Until then...

Homework Equations

Second order diff eq
damping application (I do understand critical, under, and first order)

The Attempt at a Solution

This is the attempt to get problems to work to a solution

are all of your diffy qs ODEs?

you could try a circuits book. I know the circuits book my college uses has tons of signals & systems stuff near the end of the book (that, of course, we never got to)
