1.This is a sine function of period 2. Function is sin(pi*t). Continuous Signal.
2. Periodic DT SignalThis is the discrete signal of the same function in 1 with sampling time of 0.075. I got the diagram on mat lab using the command STEM. This is periodic.
Non-Periodic DT Signal This is the non periodic DT signal of the same function in 1 with sampling time of 2. Diagram was obtained using Matlab.
