hmmm... let me think...
hmmm...
as what i know. for a LOW PASS filter, when the capacitor is an open cct, no current flows via any of the elements since they rall in series with the capacitor... the current through the resistances is zero, the voltage across them is zero... so Vi = Vo right? when the capacitor is shorted then, frequency is arbitrarily big, so the Vo = 0...
for high pass case... is it just the reverse thing? hmmm... any idea?
