hi every body,

Periodic signal g(t) is applied to RC circuits...

how can I find the fourier series?

I really do not know how can I find it from the circuit? I looked up on the internet to find sources but I couldnot find any examples or explanations that show the relation between RC circuits and seires circuits.

THank you in advance to all of you..

 

Presumably you want the Fourier series of (say) the output voltage y(t) across C in a series RC circuit in response to an input voltage g(t). Or something along those lines.....??

If so - first find the time domain steady state response y(t) and then do the Fourier series analysis of y(t).
