Driving Point Impedance

Taking the Laplace transform of both sides of Eq. (E.1) gives

where we made use of the fact that the impedance of a capacitor is , as derived above. The driving point impedance of the whole RC filter is thus

Alternatively, we could simply note that impedances always sum in series and write down this result directly.
