WebAug 18, 2014 · The crest factor is simply a number that to some extent states how dynamic a signal is. A square wave has a crest factor of 0 dB since it's the loudest possible signal, without any dynamics. There are so many factors in how you perceive the dynamics of a song that using the crest factor to represent dynamics is somewhat meaningless. Web5 Crest Factor (CF) or Peak-to-AverageRatio (PAR) in Digitally-ModulatedRF The crest factor is defined as the ratio of peak amplitude to average amplitude (Peak-to-AverageRatio) as shown in Figure 2. For narrow band QPSK modulation, the crest factor is 6 dB and for offset QPSK modulation, the crest factor is 5.1 dB.
