摘要（英）：

The invention provides an automatic gain regulator. The automatic gain regulator comprises a noise integrator, an interval time detector, a retention time timer, an RS trigger, a control logic circuitand a gain control integrator. The output end of the noise integrator is respectively connected to the input end of the interval time detector, the first input end of the hold time timer and the control logic circuit. The interval time detector is respectively connected to the RS trigger and the hold time timer. The output end of the retention time timer is respectively connected to the RS trigger and the control logic circuit. The RS trigger is respectively connected to the retention time timer and the control logic circuit. The control logic circuit is connected to the gain control integrator, and the control logic circuit is connected to the gain control integrator. Compared with the prior art, the automatic gain regulator can effectively distinguish noise and signals in infrared signals with short interval time and long total coding time, and the decoding accuracy of the automatic gain circuit to the infrared signals is high.
