Peak-to-average power ratio of signals

The Peak-to-average power ratio (PAPR) of a signal is the peak power divided by the average power.
$P A P R = \frac{x_{p e a k}^{2}}{S_{x}} = \frac{{\hat{x}}^{2}}{x_{e f f}^{2}}$

Crest factor
$C = \sqrt{P A P R}$

Peak-to-average power ratio (PAPR)

Each wave form has its particular PAPR value. Measure for different wave forms the peak amplitude and the time-averaged power. Determine the PAPR of this wave form.
