Periodic Signals
The signal x(t)=sin(t) was chosen:
Sampling at a frequency of 1 yields a non periodic signal:
Sampling at a frequency of .125*pi yields a periodic signal:
Taking a non periodic signal x(t)=log(t)and making it periodic can be done by taking a portion of the signal and repeating it over and over.
