The crest factor defines the ratio between Vp to RMS. The ideal sine wave for example has a crest factor of 1.414. Any crest factor higher than 1.414 shows additional noise, distortion or spikes. In addition the crest factor shows signal boundaries over time. White noise has a Gaussian distribution and events happening seldom are only occurring at a high crest factor. A crest factor of 7 allows you to test for a BER of 10 -12, which is required for certain standards.
