WebParseval’s Theorem (Parseval proved for Fourier series, Rayleigh for Fourier transforms. Also called Plancherel’s theorem) Recall signal energy of x(t) is E x = Z 1 1 jx(t)j2 dt Interpretation: energy dissipated in a one ohm resistor if x(t) is a voltage. Can also be viewed as a measure of the size of a signal. Theorem: E x = Z 1 1 jx(t)j2 ...
