Part A: Periodic Signals Revisited...Periodic Signals Revisited...Periodic Signals Revisited
As we discussed in class, a function x(t) is periodic if x(t+T)= x(t) , where T is a multiple of the fundamental period, or smallest period.
In the first homework, I explained how $ sin(t) $ was periodic. However, because that is rather boring, let's take a look at $ sin(t)-cos(2t) $.
