Power System Signal-Detection Method Based on the Accelerated Unsaturated Stochastic Resonance Principle

open access: yesApplied Sciences
The classical bistable stochastic resonance algorithm has an inherent output saturation defect that restricts the amplitude of the output signal. This paper examines the causes of this phenomenon and its negative impact on the detection of weak signals ...
