In mathematics, physics and engineering, the sinc function, denoted by sinc(x), has two forms, normalized and unnormalized.

A sinc filter can refer to either a sinc-in-time filter whose impulse response is a sinc function and whose frequency response is rectangular.

English: Graph of the normalized sinc function sin(πx)/(πx). Mathworld's version. The original was generated by gnuplot, while the more recent one was ...

English: Graph of both the normalized (sin(πx)/(πx)) and unnormalized (sin(x)/x) definitions of the sinc function. These are on the same scale.

Anybody have any idea how to find the Fourier Transform of Sinc2(πax) using the Convolution Theorem? ... I cannot think of any use of the 2D sinc; can anyone?

Sinc numerical methods are numerical techniques [1] for finding approximate solutions of partial differential equations and integral equations

The sinc function is used in various signal processing applications, including in anti-aliasing, in the construction of a Lanczos resampling filter, and in ...

In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle.
