A CT signal posted on Homework 1 was: x(t) = sin(t)

Periodic Signal

The New DT Signal: x[n] = sin[n] So taking that signal and making it a periodic DT signal by sampling at frequencies of n where n can only be multiples of pi.

Non Periodic Signal

The new DT Signal: x[n] = sin[n] Making this signal non periodic is by simply taking n to integer numbers, n=1, n=2, n=3, etc.

Note: This isn't an exact representation, but I did the best I could estimating the points using paint. In any case, it it possible to see that the thick lines are not periodic.
