Provided are 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 subjected to selective control output by an alternative analogue switch. When a control signal of the analogue switch is at a high level, the hybrid 0.3-order fractional integral is selected for outputting, and when the control signal of the analogue switch is at a low level, the T-type fractional integral is selected for outputting; or when the control signal of the analogue switch is at the low level, the hybrid 0.3-order fractional integral is selected for outputting, and when the control signal of the analogue switch is at the high level, the T-type fractional integral is selected for outputting. In the present invention, by adopting an alternative analogue switch, automatic switching between a 0.3-order hybrid fractional integral circuit and a 0.3-order T-type fractional integral circuit is realised, so that when the 0.3-order fractional integral circuit is used for secret communication, the complexity of the 0.3-order fractional integral is improved, and the decoding difficulty is increased, thereby facilitating the communication security. |
