| What is the weak signal detection of stochastic resonance theory? |
* Answer
| Stochastic resonance theory was originally used to explain the phenomenon of alternating glacial and warm climatic periods in meteorology. In recent years, with the development of science, people have found that the use of stochastic resonance technology for weak signal detection has a good application prospect.The stochastic resonance method is different. It uses a nonlinear system to enhance the detection of weak characteristic signals by using a mechanism that converts part of the energy of the noise into signal energy.However, people have found that in some nonlinear systems, the increase of noise not only does not further deteriorate the characteristic signals output in some specific frequency bands, but also improves the local signal-to-noise ratio of the output and enhances the appearance of the signal.A phenomenon is called “single resonance”. |
