Ormalized Classify the following signals as energy signal or power signals.

ormalized Classify the following signals as energy signal or power signals, and find the n energy or power of each. (20 points) 1) x1(t)=bcos(at) a. b. X2 (t) = a6(t-b) Xs (t) C. Consider the signal x()-2 sin abl , whose fundamental frequency is a, find the Fourier series coefficients for this signal. (hint: expand the sinusoidal signal as a linear combination of complex exponentials and identify the Fourier series coefficients by inspection)Let x2 (1) = (a + b) + cos ab-sin aart , use the same method to determin the Fourier series of it. Let x,0) = a cos aot + b sin ab, find its Fourier series. (30 points) 2)
