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: …

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 …

Jul 24, 2015 · 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 …

Apr 26, 2018 · Some programming packages (like numpy in python) provide a sinc function, presumably to sidestep this issue. But I would like to know generally if there is a better way of …

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 …

Dec 12, 2022 · It really looks like to some kind of sinc function to me, or something similar. Hence I try to approximate the Bessel function (which has a tough expression) with "nice" …

As indicated by Sean Lake, the definition of $\mathrm{sinc}$ can depend on the context. Moreover, the definition of the Fourier transform also depends on the context.
