The present invention provides a 0.5-order mixed and chained fractional order integral switching method and a circuit. A mixed 0.5-order fractional order integral and a 0.5-order chained fractional order integral are selectively controlled and output by means of a one-out-of-two analog switch. When a control signal of the analog switch is at a high level, the mixed 0.5-order fractional order integral is selected and output, and when the control signal of the analog switch is at a low level, the chained fractional order integral is selected and output; or when the control signal of the analog switch is at the low level, the mixed 0.5-order fractional order integral is selected and output, and when the control signal of the analog switch is at the high level, the chained fractional order integral is selected and output. In the present invention, by using the one-out-of-two analog switch, automatic switching is implemented between a 0.5-order mixed fractional order integral circuit and a 0.5-order chained fractional order integral circuit; and therefore, when the 0.5-order fractional order integral circuits are used in secret communications, the complexity of the 0.5-order fractional order integrals is increased and the deciphering difficulty is increased, which are advantageous for the security of communications. |
