Topics include comparison with analog transforms and discussion of Parseval's theorem. The Fourier transform of the discrete-time signal s (n) is defined to be. S(ei2πf) = ∞ ∑ n = − ∞s(n)e − ( i2πfn) Frequency here has no units. As should be expected, this definition is linear, with the transform of a sum of signals equaling the sum 4: Parseval's Theorem and Convolution Parseval's Theorem (a.k.a.
