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{...

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 …

Sinc function = spectrum of a rectangular function Interpolation can be done in many ways. The particularity of the sinc interpolation is it's the only one mathematically perfect. A function can …

As indicated by Sean Lake, the definition of sinc s i n c can depend on the context. Moreover, the definition of the Fourier transform also depends on the context.

I know that sin(x) sin (x) can be expressed as an infinite product, and I've seen proofs of it (e.g. Infinite product of sine function). I found How was Euler able to create an infinite product for …

Apr 26, 2018 · I would like to know if there is an alternate, explicit (non-iterative) form of the sinc function which behaves in a numerically stable way for all real numbers.

The sinc function is the inverse Fourier transform of the characteristic function χ[−1,1] χ [− 1, 1], at least up to a constant:
