Web5 Fourier Series Theorem • Any periodic function f (t) with period T which is integrable ( ) can be represented by an infinite Fourier Series • If [f (t)]2 is also integrable, then the series converges to the value of f (t) at every point where f(t) is continuous and to the average value at any discontinuity. f(t)dt WebFourier coefficients a k and b k. No decay Delta functions (with spikes) 1/k decay Step functions (with jumps) 1/k2 decay Ramp functions (with corners) 1/k4 decay Spline functions (jumps in f ) rk decay with r<1Analyticfunctions like 1/(2−cosx) Each integration divides the kth coefficient by k. So the decay rate has an extra 1/k.
