Abstract

A fractional order T chaotic circuit is composed of three channels. The fractional order T chaotic circuit is characterized in that an output signal of the first channel is fed back to an input end to serve as a first path of input signal connected with an input pin of a multiplying unit A2, last-level output of the first channel is connected with the input of a multiplying unit A1 and the input of the second channel, the output of the second channel is connected with the input, namely the multiplying unit A1, of the third channel, the output of the third channel is fed back to the input, and a last-level output signal is connected with the second channel and the multiplying units. The fractional order T chaotic circuit is simple in structure and reliable in performance and has an extremely important application value in image encryption and secret communication. The fractional order T chaotic circuit is suitable for university chaos science and chaotic circuit demonstration, a nonlinear circuit box and the like.

Description

technical field [0001] The invention belongs to the technical field of chaotic signal generators, and in particular relates to a fractional-order T chaotic circuit. Background technique [0002] Chaotic signals have characteristics such as randomness, initial value sensitivity, and wide spectrum, so they are widely used in security fields such as secure communication and image encryption. Among the chaotic circuits currently researched, integer-order chaotic circuits such as classic Lorenz circuits, Chen circuits, LV circuits, etc., but some fractional-order chaotic circuits are still being discussed and studied, and fractional-order differentials are introduced into chaotic systems, making chaotic systems It has more complex chaotic motion characteristics, so the research on fractional order chaotic circuits has immeasurable research value and application value. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the...
