Crest factor of 3:1
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. Webfactor.

Thus a sinusoid has a crest factor of 1/√2, a triangle or sawtooth wave has a crest factor of 1/√3, and a square-wave has a crest factor of 1. It is typically used when specifying true RMS meters, as there is a limit to the value of crest ... WebJan 19, 2024 · For other applications, consider an audio amplifier designed to handle an RMS signal of 1 volt at the input. If we didn't understand anything about the crest factor of the actual signal into the amplifier, we might design it to work with 1 volts RMS sinewaves and neglect the fact that for an audio signal, the crest factor is quite high.
WebCrest factor can be thought of as an alternative to kurtosis, characterized by greater focus on the influence of the largest impulses in the data and, as such, neglect (to some extent) of the importance of other, lower amplitude peaks.
