1. The coefficients of a standard trigonometric Fourier series for a signal x(t) are given below. ao = 0, am = 0, bm where A is the amplitude of the signal. a) Write the equation for the signal x(t) in both standard trigonometric and compact form. b) Plot the signal x(t). Consider A=4, m=1:10, time interval te [-2, 2] and a sampling frequency F = 100 Hz and fundamental frequency fo = 2 Hz. What signal is this? c) Plot the spectral representation of the signal x(t) (Use 'Stem' command in Matlab). Does the spectral plot show odd, even, or both odd and even components? MUT
