Description

technical field [0001] The invention belongs to the field of nonlinear circuits, in particular to a time-delay neural network hyperchaotic circuit. Background technique [0002] Neural network is a kind of complex dynamic system, and the system can show chaotic characteristics by choosing appropriate parameters. Neural network circuit is an important part of nonlinear circuit. Because of its strong concealment, chaotic neural network circuit can have great use value in secure communication and image processing. The current neural network circuit considers the normal working state, but in the actual circuit, most of them have a lot of interference. Therefore, the hyperchaotic neural network with impulsive effect can better reflect the impulsive interference in the actual circuit, and has better adaptability in secure communication. Contents of the invention [0003] The object of the present invention is to propose a time-delay hyper-chaotic neural network circuit, which ...
