ABSTRACT OF THE DISCLOSURE A very rapidly converging adaptive filter which uses a variable scale factor for each weight of the filter. The size of the variable scale factor is chosen for each iteration and is based upon the sign changes of the in- cremental weight change. The variable scale factor permits large step sizes when no sign changes occur and smaller step sizes when sign changes occur. The new filter provides considerable improvement in convergence rate and residual errors even in the presence of heavy noise while requiring only a modest increase in hardware.
