  1. 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{...

  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. 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...

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

    Jan 20, 2015 · Fourier transform of sinc function. Ask Question Asked 11 years ago Modified 1 year, 8 months ago

  5. Dirac delta function as a limit of sinc function

    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 …

  6. 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 …

  7. 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?

  8. Normalized sinc(at) - Mathematics Stack Exchange

    Jan 31, 2017 · I came across the definition of the sinc function when it is normalized as sinc(t)= sin(pi.t)/pi.t. So if we scale the argument of the normalized sinc function as sinc(at), will that equal …

  9. terminology - What is the etymology of 'sinc function'? - Mathematics ...

    Feb 11, 2013 · The term "sinc" is a contraction of the function's full Latin name, the sinus cardinalis (cardinal sine) It was introduced by Phillip M. Woodward in his 1952 paper "Information theory and …

  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
