1. Creating two DT signals (one periodic and one non-periodic) from a periodic CT signal
Let x(t) = sin (t), which is a periodic CT signal
x(t) = sin (t)
Sampling every t = 0.01
Periodic Signal
Sampling every $ t = \pi $
As can be seen from the graph, the values of x[n] are periodic because they repeat after every period of $ t = 2\pi $
Non Periodic Signal
Sampling every t = 1
