Abstract

The invention discloses a chaotic circuit capable of realizing amplitude-frequency control by a time constant. Integration-summation circuits of three branches are taken as a framework, and three paths of chaotic signals are output through internal feedback circuits of five multipliers and an internal linear feedback item. Through adjustment of resistance or capacitance on a first-dimension linear feedback branch, joint adjustment and control of the amplitudes and frequencies of the chaotic signals output by a system is realized. The amplitudes and frequencies of the chaotic signals output by the circuit are adjusted through rheostats and adjustable capacitors of the branches to realize joint adjustment and control of the amplitudes and frequencies. Joint control of the amplitudes and the frequencies is implemented through two control entries different from other circuits, so that the flexibility of a hardware circuit is enhanced; the circuit implementation and debugging difficulty is lowered; and convenience is brought to application of the chaotic signals to electronic and information engineering.

Description

technical field [0001] The invention belongs to the technical fields of electronics, communication and information engineering, and particularly relates to a chaotic circuit which can realize amplitude-frequency control with a time constant. Background technique [0002] As a kind of broadband random signal, chaotic signal has a wide range of applications in fluid stirring, search and prediction, instrumentation, communication, radar and other fields. The amplification or attenuation of the signal amplitude and the scaling of the frequency used in engineering are not only the needs of signal conditioning, but also an important indicator to characterize the characteristics of circuit parameters. The amplitude and frequency change of chaotic signal is the basic task of signal preprocessing or conditioning circuit, and it is also an important link to reduce redundant circuit components or additional systems and simplify the circuit. The amplitude-frequency control of chaotic si...
