The invention provides a 0.3-order hybrid and T type fractional integral switching method and circuit. A hybrid 0.3-order fractional integral and a 0.3-order T type fractional integral are selectively controlled and output by use of a one-out-of-two analogue switch; when the control signal of the analogue switch is at a high level, the hybrid 0.3-order fractional integral is selected and output, and when the control signal of the analogue switch is at a low level, the T type fractional integral is selected and output; or when the control signal of the analogue switch is at the low level, the hybrid 0.3-order fractional integral is selected and output, and when the control signal of the analogue switch is at the high level, the T type fractional integral is selected and output. According to the 0.3-order hybrid and T type fractional integral switching method and circuit, the one-out-of-two analogue switch is adopted to realize automatic switching of a 0.3-order hybrid fractional integral circuit and a 0.3-order T type fractional integral circuit, and therefore, when the 0.3-order fractional integral circuits are applied to secret communication, the complexity of the 0.3-order fractional integrals is improved and the difficulty of deciphering is increased, which are advantageous for the security of communications.
