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).
