hello,
I'm new here and since I can't ask in the Theory sections, I figured I'll ask here.. sorry if that's not ok..
I've heard of this concept "impedance" and the teachers I came across told me that it's similar to resistance, so that wasn't hard to get..
Then when we studied op-amps, I see terms like "input impedance" and "output impedance"..
I read this description which seems to be simple and easy to digest
impedance
but I still don't know what we mean by "input and output impedance" when talking about op-amps (or any other devices).. Anyone cares to share what they think is correct?
thanks,
~dyf
