The term sinc /ËsÉªÅk/ is a contraction of the function's full Latin name, the sinus cardinalis (cardinal sine).he local maxima and minima of the unnormalized sinc correspond to its intersections with the cosine function. That is, sin(Î¾)/ Î¾ = cos(Î¾) for all points Î¾ where the derivative of sin(x)/ x is zero and thus a local extremum is reached.
