摘要：
A self-calibrating signal strength detector is described. The present invention utilizes a relatively narrow dynamic range receiver sensitivity threshold indicator circuit to calibrate the output signal of a relatively wide dynamic range signal strength detector. In accordance with the present invention, a processing device monitors the outputs of the signal strength detector and receiver sensitivity threshold indicator circuit simultaneously, and determines a correction factor to be applied to the output of the signal strength detector when the receiver sensitivity threshold indicator circuit indicates that a received signal is at the receiver sensitivity threshold.
