# Peak-to-average power ratio of signals

To launch labAlive simulation applications you need a Java Runtime Environment supporting Java Web Start on your system. Here you can get more information about installing the right Java version.

The Peak-to-average power ratio (PAPR) of a signal is the peak power divided by the average power.
$PAPR=xpeak2Sx=x^2xeff2$

Crest factor
$C=PAPR$

Waveform $PAPR$ $PAPR|dB$
DC 1 0 dB
Square 1 0 dB
Sine 2 3,01 dB
Cosine 2 3,01 dB
Triangle 3 4,77 dB
Sawtooth 3 4,77 dB
Audio signal 80 19 dB
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.
