Description

technical field [0001] The invention relates to a multi-scroll chaotic signal generating device. The device is based on a Jerk circuit form and adds a function generating module and an addition and subtraction circuit module to form a multi-scroll chaotic signal source. Background technique [0002] Ordinary signal sources can generate periodic signals with different waveforms, and have been widely used in the field of information engineering. The characteristic of periodic signal is that it is convenient for the synchronization of modulation and demodulation, but it is not conducive to the requirements of special fields such as information encryption. Chaotic signals have the characteristics of inherent randomness, initial value sensitivity, broadband, ergodicity, and boundedness, and can generate broadband signals similar to white noise. Therefore, chaotic signals have a wide range of applications in the fields of information encryption, secure communication, and chaotic r...
