WebSep 23, 2024 · The Sinc Function in Signal Processing. The Fourier transform of the sinc function is a rectangle centered on ω = 0. This gives sinc (x) a special place in the realm of signal processing, because a rectangular shape in the frequency domain is the idealized “brick-wall” filter response. In other words, sinc (x) is the impulse response of an ...
