Part 1

Periodic signal Sampling the signal at a frequency that is a rational multiple of the frequency of the signal will result in a periodic Discrete Time signal. Sampling the signal at a frequency that is not a rational multiple of the frequency of the signal will result in a non-periodic Discrete Time signal.

My all time favorite CT periodic signal- Sin(t)

t  = 0:0.02:10; 
x = sin(t);
plot(t,x)
