Random operational signals recorded during control system evaluation tests or equipment vibration surveys are often reduced to power spectral curves or related quantities such as transfer functions so that the distribution of signal amplitude as a function of frequency will be evident. However, meaningful power spectral quantities are only valid for stationary data. This report discusses theoretical aspects of stationarity, and investigates the application of the most significant stationarity test, the run test, to randomly varying signals. Run test procedures and implementation are outlined and applied. Author
