Pink noise is another commonly seen input signal used for thermal tests. Pink noise is a type of noise signal where each octave interval carries an equal amount of energy. One advantage of using pink noise is that it better simulates the various levels of dynamic range in music signals as well as testing the device across different frequencies.
Pink noise, unlike sinusoidal signals, can have a varying crest factor. The crest factor is the difference between the peak value to the RMS value in the waveform.
