MEASUREMENT OF QUASISTATIONARY RANDOM SIGNAL ENVELOPE

V.Augutis, Ž.Nakutis
Abstract:
Signals of quasistationary nature are often met in diagnostics and NDT systems. In the paper model for quasistationary signals with periodically varying deviation is proposed. Procedures for wide band quasistationary signal envelope detection are analyzed and tested using both simulated signals and records of Barkhausen noise. Accuracy and speed of detection of these procedures are estimated using digital signal processing techniques.
