Problem 1. For a continuous-time signal s(t), we define the energy of the signal as E and the power of the signal as P = „lim Is(t)dt. (a) Find the energy and the power of s(t) = Am Cos(27 mt). (b) Find the power of 8(t) = Am Cos(27 fmt) + A, cos(27 fSut), In = k fms where k is an integer # {0, 1}. (c) Find the energy and the power of the signal s(t) = Asinc(t).
