What Is Crest Factor?

Source: Wireless Telecom Group

When testing wireless systems and devices, it is crucial to calculate the crest factor, an important ratio. Digital modulation schemes, such as orthogonal frequency-division multiplexing (OFDM), usually have high crest factor values. This metric can be utilized in various ways, such as detecting amplifier nonlinearity by comparing the crest factors of an amplifier’s input and output signals. If you're curious about what crest factor is, you can learn more in this video.
