The paper proposes a new control algorithm of digital AGC. The algorithm overcomes the limitation that the control range and control precision of AGC chip can not meet the engineering requirement,and solves the problems that are not processed by other algo rithms. The paper describes the algorithms of power calculating and power filtering of the input signal, as well as the adjusting algorithm of control range and control precision, and presents the AGC control process diagram based on the new algorithm. It also analyses the per formance of the power calculating algorithm,performs simulation of the filter,and verifies the control range and control precision.
