PROBLEM TO BE SOLVED: To converge the receiving level of a digital converted received signal to a target convergence without diffusing or oscillating. SOLUTION: A convergence coefficient determinator 104 makes a threshold decision using a preset threshold concerning a mean value calculated by a mean value calculator 103 and determines a convergence coefficient. A gain coefficient determinator 106 determines a control gain on the basis of the convergence coefficient and the mean value. A gain/voltage converter 107 converts a gain coefficient to voltage and finds a control voltage. According to the digital converted control voltage, a GCA 101 amplifies the received signal. |
