Fig. 1From: Electrical transient modeling for appliance characterizationTwo examples of transients. a A (turn-on) transient of an electrical signal (drill) for which the superimposed damped sinusoids (SDS) model is inadequate, and b a transient of an audio signal (castanets) for which the SDS model is adequate. Note the non-stationary content of b and the quasi-stationary content of aBack to article page
