How do you calculate crest factor?
One key parameter derived from the two values mentioned above is crest factor, which is the ratio of the peak value to the root-mean-square (rms) value of a waveform. This is expressed by the equation C = XPEAK ÷ XRMS.
What is RMS crest factor?
Crest factor is the peak amplitude of the waveform divided by the RMS value of the waveform. The peak-to-average power ratio (PAPR) is the peak amplitude squared (giving the peak power) divided by the RMS value squared (giving the average power). It is the square of the crest factor.
What is crest factor in audio?
Crest factor, defined
Simply stated, crest factor—sometimes called peak-to-average ratio—is the difference in decibels between the peak and average levels of a signal.
