Random
A random signal contains energy spread over a band of frequencies rather than concentrated at discrete frequencies. Random signals are commonly called random noise, and a good example is the noise heard on an FM radio receiver when tuned off station. Most vibration signals from machines contain a certain amount of random noise in addition to the desired vibration signature.
