What is the Fourier transform of sinc?

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.

What is sinc function and sampling function?

The sinc function , also called the "sampling function," is a function that arises frequently in signal processing and the theory of Fourier transforms. The full name of the function is "sine cardinal," but it is commonly referred to by its abbreviation, "sinc." There are two definitions in common use.

How do you plot a sinc function?

The sinc function is the continuous inverse Fourier transform of the rectangular pulse of width and height 1. for all other elements of x . To plot the sinc function for a linearly spaced vector with values ranging from -5 to 5, use the following commands: x = linspace(-5,5); y = sinc(x); plot(x,y)
