Paper Title:
SR Recovery Methodology Based on the Signal Classification
  Abstract

A method to recover the distorted signal in the bistable stochatic resonance(SR) system is proposed.This paper investigates the movement track of a particle in the bistable system and the suggested recovery system. In terms of the spectrum feature, we define the series of methods as the SR recovery methodology based on the signal classification. The signal is classified as the sinusoid-alike signal or the pulse-alike signal. To the sinusoid-alike signal, a cascaded-bistable system was introduced to genrate the second tuning for the residual noise and the recovery system with the parametric tuning was applied to restore the output waveform;For the pulse-alike signal ,a mono-stable system was introduced for the residual noise and the recovery system with the parametric fixed was applied to restore the output waveform. The engineering experiments has presented that it can recover the weak information submerged in noise effectively.
