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{...

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 …

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...

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 …
