WebA sinc function is an even function with unity area. 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. WebFeb 23, 2001 · The sinc function is defined as . sinc(x) = sin(πx)/πx for x different from 0; sinc(x) = 1 for x = 0.The motivation for attributing the value 1 to sinc(0) is of course the fact that even if sin(x)/x is not defined at x = 0, lim x->0+ sinc(x) = lim x->0-sinc(x) = 1..
