''The sinc function, also called the "sampling function," is a function that arises frequently in signal processing and the theory of Fourier transforms. The full name of the function is "sine cardinal," but it is commonly referred to by its abbreviation, "sinc." There are two definitions in common use. An interesting property of is that the set of local extrema of corresponds to its intersections with the cosine function, as illustrated above.''https://mathworld.wolfram.com/SincFunction.html
