Consider the funcțion
if -a <a <0
if x = 0
f(x) =
if 0 <x <a
(a) Plot the Nth partial sum the Fourier sine series of f(æ) for N = 5, 10, 50, and 200
along with ƒ (x) for -a < ¤ < a.
(b) Show that each of the maximum overshoots occurs near a discontinuity and that
they approach a limit which is approximately 9% more than the magnitude of the
jump at the discontinuity. This behavior is the Gibbs Phenomenon that was
mentioned in the class.
