1. Determine the average power and energy of the following continuous-time signals:
(a) x(t) = ej(2t+ 4 )
The signal is perodic thus its average energy is infinite.
The average power of the signal is:
P = lim
Since x5[k ] is a finite duration signal of length 16 with finite magnitude, it must be an energy
The total energy in x5[k ] is given by
( 2 ) + 1 = 4 1 + 5 = 1398106
The average power Px
1. Determine whether or not each of the following continuous-time signals is periodic. If the
signal is periodic, determine its fundamental period.
(a) x(t) = 3 cos(4t + 3 )
Continuous sinusoids are always periodic. The period
