Abstract

The invention discloses a fourth-order monostable stochastic resonance circuit, and relates to the technical field of signal processing devices. The resonance circuit comprises a main circuit and a feedback circuit, wherein the main circuit comprises an adder and an integrator; the feedback circuit comprises an amplifier module and a multiplier module; an input end of the adder inputs a to-be-processed voltage signal; an output end of the adder is connected with the input end of the integrator; the output end of the integrator is divided into two paths; one path is a signal output end of the resonance circuit and the other path is a feedback signal output end; the feedback signal output end is connected with the input end of the amplifier module; and the output end of the amplifier module is connected with a feedback signal input end of the adder through the multiplier module. The resonance circuit structure becomes simple when the output characteristics of the system are ensured; and reduction of the order of magnitude of the system parameter is facilitated by adjusting the structure of the circuit.

Description

technical field [0001] The invention relates to the technical field of signal processing devices, in particular to a fourth-order monostable stochastic resonance circuit. Background technique [0002] Stochastic resonance theory is a new signal processing method developed in the past 30 years. It utilizes the characteristics of noise instead of suppressing noise, and provides a new idea for feature extraction of weak signals. The bistable stochastic resonance model is a classic model of stochastic resonance theory, which is widely used in biology, chemistry, machinery and other fields. In practical applications, it is often difficult to determine the adjustment direction of the two system parameters of the bistable stochastic resonance circuit to quickly reach the resonance state, and the magnitude of the final parameters will vary greatly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fourth-order monostabl...
