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 …

WitrynaThe true impulse has a much different magnitude spectrum. It is a constant value across all frequencies between 0 and fs /2 Hz. Its phase spectrum is also a constant.
