Consider the periodic fiunction s() with time period tas shown in the fugure below: the spikes are located at (2-1), where n=0,t1, 12.. are dirac delta function

Consider the periodic fiunction S() with time period Tas shown in the fugure below: The spikes are located at (2-1), where n=0,t1, 12.. are Dirac delta functions of strength +1. The amplitudes a, in the fourier expansion J0)= 2a, are given by - (-1) (b)-sin 2T (O T 2 (c) isin ) nr
