Choose the function f(t) ; −∞ < ???? < +∞, for which a Fourier series cannot be defined.
(a) 3 sin(25t????) (b) 4 cos(20????t + 3) + 2 sin (10t????)
(c) e-|t| sin(25t) (d) 1
fourier series are available for all periodic signal .its obvious that all the four are periodic.But somewhere i hear that fourier series is not possible for constant .could someone give me hint for the answer ,so try to come up. Thank you
