A sinc pulse passes through zero at all positive and negative integers (i.e., t = 1, 2, ), but at time t = 0, it reaches its maximum of 1.This is a very desirable property in a pulse, as it helps to avoid intersymbol interference, a major cause of degradation in digital transmission systems. The rectangular function is an idealized low-pass filter, and the sinc function is the non-causal impulse response of such a filter. That process is also called analysis. This mask is converted to sinc shape which causes this problem. In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a complex-valued function of frequency. A Fourier transform (FT) is a mathematical transform that decomposes functions into frequency components, which are represented by the output of the transform as a function of frequency. The sinc function sinc(x), also called the "sampling function," is a function that arises frequently in signal processing and the theory of Fourier transforms. : Fourier transform FT ^ .
