Definition of Sinc function - Mathematics Stack Exchange
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{...
How does sinc interpolation work? - Mathematics Stack Exchange
Sinc interpolation is basically just supersampling by padding your spectrum and transforming back (with higher frequencies, the sample rate is now shorter and you get intermediate values). It's what you …
Fourier transform of sinc function - Mathematics Stack Exchange
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...

integration - Derive Fourier transform of sinc function - Mathematics ...
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
Dirac delta function as a limit of sinc function
Jan 2, 2015 · A related proof is by Fourier transforms. Here's a sketch of this proof: The sinc function (with appropriate scaling) is the Fourier transform of the indicator function of an interval centered at …

Is the Sinc function continuous? - Mathematics Stack Exchange
Jul 4, 2015 · An (arguably) elegant way to avoid any discontinuity problems is to define sinc as the Fourier transform of the box function. Since that is compactly supported, its transform is continuous …
Definite Integral of sinc function - Mathematics Stack Exchange
Aug 27, 2017 · The normalized sinc sinc function can be integrated similarly, except you will have to first use a change of variable on the integral in order to apply the definition of the Sine Integral.
