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 ). [1] It is the square of the crest factor. When expressed in decibels, crest factor and PAPR are equivalent, due to the way decibels are calculated for power … See more Crest factor is a parameter of a waveform, such as alternating current or sound, showing the ratio of peak values to the effective value. In other words, crest factor indicates how extreme the peaks are in a waveform. Crest … See more • Electrical engineering — for describing the quality of an AC power waveform • Vibration analysis — for estimating the amount of impact wear in a bearing See more Many modulation techniques have been specifically designed to have constant envelope modulation, i.e., the minimum possible crest factor of 1:1. In general, modulation techniques that have smaller crest factors usually transmit more bits per … See more • Clipping (signal processing) • Form factor (electronics) See more • Definition of peak-to-average ratio – ATIS (Alliance for Telecommunications Industry Solutions) Telecom Glossary 2K • Definition of crest factor – ATIS (Alliance for Telecommunications Industry Solutions) Telecom Glossary 2K See more WebSep 19, 2024 · To determine the crest factor, the challenge becomes to first figure out the waveform's "average" which — for our application — we will attempt in two ways.
