Speaking in a random fashion
Abstract
In order to understand a random signal, its characteristics must be determined, taking into account its intensity and its frequency content. A successful approach to accomplish this involves the measurement of the standard deviation and the spectral density of the signal. The present investigation is concerned with the theory concerning random signals, the characteristics of the parameters, and details regarding the testing procedure. Attention is given to the difference between a random signal and a complex signal, the use of a mathematical theory developed by Gauss for measuring the signal strength of a random signal, the study of the frequency characteristics of a random wave, aspects of sine wave equivalency, and problems of random vibration testing.
