Webfor all real a ≠ 0.. The normalization causes the definite integral of the function over the real numbers to equal 1 (whereas the same integral of the unnormalized sinc function has a value of π).As a further useful property, the zeros of the normalized sinc function are the nonzero integer values of x.. The normalized sinc function is the Fourier transform of … WebA trigonometric polynomial is equal to its own fourier expansion. So f (x)=sin (x) has a fourier expansion of sin (x) only (from [ − π, π] I mean). The series is finite just like how the taylor expansion of a polynomial is itself (and hence finite). In addition, b n = 0 IF n ≠ 1 because your expression is undefined for n = 1.
