A computer program is presented that calculates the probability density function, autocorrelation function, power spectral density, and cross-correlation function. The program has the capability of accepting data from any stationary random process such as turbulence, aerodynamic flutter, cavity flow, or pressure wave analysis. The program accepts digitized data and processes the data via user controls producing both tabulated and graphical displays. The program was written in Fortran IV, verified and tested, and is now operational. It was verified by a standard signal of known composition and also an experimental data signal which was analyzed by other techniques and compared. The program is not limited to fluid flow analysis.
