b) Consider the signal, x(t) = 10 cos(30nt) + 20 cos(60tt) + 30 cos(907). Give the value of the fundamental frequency we of this signal, and write the expression for x(t) as an exponential Fourier series of the form, X(t) = ?k=-o akejkwot. Determine the values of the axe coefficients. State the number of ax coefficients that have non-zero values, and write an explanation for this number.
