ABSTRACT:
Input average levels and output average levels of digital channel filters217and218are computed in amplitude calculation circuits101and102. In a gain difference calculation circuit103, a gain difference of the input levels and the output levels is computed as a multiplier α so that a difference between the input levels and the output levels are eliminated or adjusted to be within a certain value. The outputs of the digital channel filters217and218are multiplied by the multiplier α in multiplier units104and105. The multiplication results are outputted as corrected digital signals to a subsequent digital signal processing circuit.
