The present invention provides a 0.5-order chained and T type fractional order integral switching method and a circuit. A chained 0.5-order fractional order integral and a 0.5-order T type 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 chained 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 T type fractional order integral is selected and output; or when the control signal of the analog switch is at the low level, the chained 0.5-order fractional order integral is selected and output, and when the control signal of the analog switch is at the high level, and the T type 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 chained fractional order integral circuit and a 0.5-order T type 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. |
