  1. 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...

  2. How does sinc interpolation work? - Mathematics Stack Exchange

    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 …

  3. 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{...

  4. Integration of the cardinal sine - Mathematics Stack Exchange

    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 $0$ …

  5. Fourier transform of sinc function. - Mathematics Stack Exchange

    Jan 20, 2015 · Fourier transform of sinc function. Ask Question Asked 11 years, 2 months ago Modified 1 year, 9 months ago

  6. sinc function centered at $x=c$ that goes to zero at $x=0$?

    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?

  7. Similarities between the Bessel $J_0(x)$ function and the sinc functions

    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" trigonometrical functions.

  8. Sinc function vs Dirichlet kernel - Mathematics Stack Exchange

    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 …

  9. functional analysis - sinc function in terms of Hermite function ...

    Dec 15, 2011 · sinc function in terms of Hermite function Ask Question Asked 14 years, 3 months ago Modified 11 years, 1 month ago

  10. integration - Derive Fourier transform of sinc function - Mathematics ...

    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
