The operation of convolution has the following property for all continuous time signals x 1, x 2 where Duration ( x) gives the duration of a signal x. (3.4.16) Duration ( x 1 ∗ x 2) = Duration ( x 1) + Duration ( x 2) In order to show this informally, note that ( x 1 ∗ x 2) ( t) is nonzero for all tt for which there is a τ such that x 1. Just as with discrete signals, the convolution of continuous signals can be viewed from the input signal, or the output signal.The input side viewpoint is the best conceptual description of how convolution operates. In comparison, the output side viewpoint describes the mathematics that must be used. These descriptions are virtually identical to those presented in Chapter 6 for discrete signals In mathematics, the convolution theorem states that under suitable conditions the Fourier transform of a convolution of two functions (or signals) is the pointwise product of their Fourier transforms. More generally, convolution in one domain (e.g., time domain) equals point-wise multiplication in the other domain (e.g., frequency domain).Other versions of the convolution theorem are.
