PROBLEM TO BE SOLVED: To provide an adaptive step size control adaptive filter that is easily realized with a high convergence speed and a small residual error after the convergence and to provide an adaptive step size control method. ;SOLUTION: The adaptive step size control adaptive filter employing the probability gradient sine algorithm has a leakage accumulator 37 that receives a signal resulting from multiplying a signal delaying a sum of an error signal and an additive noise by a unit time by polarity of a sum of the error signal and the additive noise and a value obtained by multiplying a prescribed coefficient by an absolute value of the signal updated by the leakage accumulator 37 is used for a step size.;COPYRIGHT: (C)2000,JPO
