Hi i am going through a book called Signals & Systems by Oppenheim and willsky.I have a doubt regarding complex exponential signal e^jωot.
The difference between continuous time and discrete time exponential signal is mentioned to be that the continuous time signals for each value of ωo are unique whereas they repeat with an interval of 2∏ for discrete time.
Considering above discursion if we plot exponential signal using eulers theorem if if we plot cos(∏/2) and cos(5∏/2) they should be unique but they appear to be same....how is it?
Please solve this doubt of mine...
