Ok. So I have an assignment consisting of a BJT circuit, but questions about that will come later. Connected to the emitter of the BJT is a resistance R1 in parallel with capacitor C, then these are in series with resistance R2 to ground.
(I need to perform small signal analysis so C won't be treated as a short)
I know that R1 in parallel with C is just R1+Zc, and R1 in series with R2 is R1+R2. I'm just not sure what the total impedance is supposed to be. At first I thought it should just be (R1+Zc) + R2 but that doesn't seem right, since R2 is in series with C in a way. Would the equivalent impedance be (R1||R2)+Zc?
Any help is much appreciated!
