I am trying to grasp properly the concepts of output impedance and input impedance.
/edit
Please, forget I mentioned input impedance.
/edit
Regarding the first (output impedance), I think I have a minimal idea but trying to calculate it in a real case, I fail miserably.
For the attached circuit I need to know the source impedance.
My questions:
a) Given the filter, what is the source impedance? Can you tell briefly how do you calculate (or just estimate) it?.
b) If I apply Vout (as Vsig) to the resistive divider, what is the source impedance at the output where I get Vdiv? Can you tell again, how do you calculate (or just estimate) it?
Gracias for any help on this.
