Abstract

The invention provides a 0.9 order mixed type and chain type fractional order integral switching method and circuit. A mixed type 0.9 order fractional order integral and a 0.9 order chain type fractional order integral are selectively controlled and output by an alternative analog switching device, when the control signal of the alternative analog switching device is a high level, the mixed type 0.9 order fractional order integral is selected and output, when the control signal of the alternative analog switching device is a low level, the chain type fractional order integral is selected and output, or when the control signal of the alternative analog switching device is the low level, the mixed type 0.9 order fractional order integral is selected and output, and when the control signal of the alternative analog switching device is the high level, the chain type fractional order integral is selected and output. The alternative analog switching device is used by the method and circuit provided by the invention for automatically switching the 0.9 order mixed type fractional order integral and the 0.9 order chain type fractional order integral, when the 0.9 order chain type fractional order integral is applied to secret communication, the complexity of the 0.9 order fractional order integral is increased, the decoding difficulty is increased, and the communication security is improved.
