The Paley-Wiener integral is a mathematical concept used primarily in the field of signal processing and Fourier analysis. It is associated with the analysis of functions that are band-limited, meaning that they contain no frequencies higher than a certain maximum frequency. The Paley-Wiener integral is particularly important in the study of the properties of these functions in relation to the Fourier transform.
