What is a sinc function used for?
The normalized sinc function is the Fourier transform of the rectangular function with no scaling. It is used in the concept of reconstructing a continuous bandlimited signal from uniformly spaced samples of that signal.
What is sinc function in digital image processing?
In signal processing, a sinc filter is an idealized filter that removes all frequency components above a given cutoff frequency, without affecting lower frequencies, and has linear phase response. The filter's impulse response is a sinc function in the time domain. and its frequency response is a rectangular function.
How do you define a sinc function in Matlab?
Viewed as a function of time, or space, the sinc function is the inverse Fourier transform of the rectangular pulse in frequency centered at zero, with width 2 π and unit height: sinc x = 1 2 π ∫ - π π e j ω x d ω = sin π x π x , x ≠ 0 , 1 , x = 0 .
