Abstract
The automatic gain controller is comprised of a multiplier for multiplying an input signal by a given AGC multiplication factor to produce an output signal. An adder is provided for subtracting a target value from the output signal and adding an integrated value of an error value from the adder to the output signal to produce error value. An integrator to compute the integrated value of the error value from the adder. An operator is provided for computing a compensation value based on the error value according to a predetermined polynomial. An accumulator is provided for producing said AGC multiplication factor according to the compensation value. The automatic gain controller is composed of a digital signal processor specifically programmed to functionally constitute those of the multiplier, the adder, the operator, and the accumulator.
