Homework Statement
This is seriously going to drive me insane. I know that a time changing B field produces a curling E field. For case #1, I have an open circuited loop with a B field increasing out of the page. This should create a polarity indicated in my picture.
I hook up a load...

The Attempt at a Solution
I've attached a picture of my work. I'm a bit confused as to how I would be able to make that simplification towards the end...
yeah not the best english student!
basically if the system has input u[n] and output cos[n], then is that system causal?
Because the output has values for n<=0 whereas the input only has values for n>=0.
Therefore the output is anticipating the input? That's bascially my question.
Hey guys, having a little trouble understanding whether or not a system is causal or not. I d'nt think this classifies as homework; at least I hope not.
Basically I'm confused as to how you would go about determining whether or not a system is causal.
For example, say any function x[n] =...
