SYSTEMS FOR THE COLLECTION AND ANALYSIS OF DYNAMIC DATA.

Abstract

The machine errors are discussed of equipment used for the conditioning, collection, recording, editing, and analysis of data from dynamic processes such as acoustics, strain, or vibration. The specific equipment items studied include special features of signal conditioners (e.g., automatic gain control), signal conditioner to tape recorder transmission line, magnetic tape recorders, gross analyzers (e.g., voltmeters), frequency analyzers, amplitude analyzers, and time domain analyzers. (The machine errors associated with transducers and basic signal conditioners are presented in 'Transducers for Sonic Fatigue Measurements.') Where these errors are controllable, such as the smoothing error associated with the rate of scanning an amplitude window for probability density measurements, pertinent equations are presented for determining the magnitude of these errors as a function of the controllable parameter(s). In addition, the report describes practical usage of the analysis equipment for the detection of non-normality, nonstationarity, and periodicity. (Author)
