A Digital System for the Acquisition and Analysis of Random Data
Statistical methods of analysis are used to obtain important physical properties of random signals. A description is given of the system which was designed for use in the Propulsion Wind Tunnel, Arnold Engineering Development Center, to provide the necessary signal conditioning and the analog-to-digital conversion at a rate high enough to prevent mixing of the spectral densities. The overall system transfer function is discussed, and the system limitations are defined.
