    Hello.
    I'm having trouble determining is a CT signal is periodic.
    For example, e^j(pi*t-1)
    I'm aware that x(t) = x(t+T) where T is a positive value that shift the property while leaving it unchanged. I'm just stumped of how to find that period.

    I know that sin and cos are always periodic, but can someone go step by step on how to determine the period of this problem? Im really interested in the method of how to solve problems like this. (the period is 2pi/pi = 2)
    Thanks.
