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{...

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 …

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...

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?

Nov 25, 2024 · Looking at the generality of results like the central limit theorem, as well as questions like this - is it just incidental that $\text {sinc}$ was the function I happened to be messing around with …

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 …

Mar 12, 2021 · The integral of $\text {sinc}\ x=\dfrac {\sin\pi x} {\pi x}$ is 1. Indeed the Fourier Transform of $\text {sinc} (x)$ is the $\text {rect} (x)$ function, which is $1$ for $|x| < \frac {1} {2}$ and $0$ …
