The signal [tex] x(t) = e^{jt} [/tex] is periodic.
The signal [tex] x(t) = e^{-t}e^{jt} [/tex] is not periodic.
The decaying exponential makes the complex exponential decay and converge toward zero, but why is it not periodic?
Also, this signal is not considered time limited since it never actually reaches zero. Right?
