Let us consider the Fourier transform of $\\mathrm{sinc}$ function. As I know it is equal to a rectangular function in frequency domain and I want to get it myself, I know there is a lot of material...

Convolution with sinc pulses What we want to do to reconstruct the signal is a convolution between the samples and scaled and shifted versions of sinc. This technique is known as Whittaker–Shannon …

I just want to make clear of the definition of sinc(x). I know there is a normalized and unnormalized definition for the sinc function. If we have unnormalized sinc then we have: $$\\sin(x)/x=\\text{...

Apr 12, 2017 · I want a sinc function that is shifted away from the origin such that it's centered at some value $c$, and also equals zero at $x=0$. How can I define this function?

Thank you for your reply! Convolution of a function with the Dirichlet kernel produces the partial sum representing the function after forward and inverse Fourier transform. Does it make any sense to call …

Dec 12, 2022 · I only consider here the Bessel function of the first kind, which is J0(x) J 0 (x). It really looks like to some kind of sinc function to me, or something similar. Hence I try to approximate the …

Jan 2, 2015 · The sinc function (with appropriate scaling) is the Fourier transform of the indicator function of an interval centered at $0$. The delta function is the Fourier transform of the constant …

Apr 24, 2012 · We know that the Fourier transform of the sinc function is the rectangular function (or top hat). However, I'm at a loss as to how to prove it. Most textbooks and online sources start with the

Jan 31, 2017 · I came across the definition of the sinc function when it is normalized as sinc(t)= sin(pi.t)/pi.t. So if we scale the argument of the normalized sinc function as sinc(at), will that equal …
