W(t) 45 4 (s) 4.5 -3.5 -25 -1.5 3.5 -05 25 2 0.5 1 15 3. The above periodic signal w(t) is multiplied with sin(2nt) to generate the signal f(t) = w(t)sin (2nt). For the periodic signal f(t), specify the symmetry (if any) and as well as the value for wo so as to find the Fourier series (12 pts) determine all coefficients representation of f(t) in the following forms A. f(t) = ao + ancos(nast) + bnsin(na,t); n-1 B. f(t) = Cpelnwt Zna-o
