Periodic Signals

The signal x(t)=sin(t) was chosen:

Sampling at a frequency of 1 yields a non periodic signal:

HW2A2 ECE301Fall2008mboutin.png

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.
