method and schaltungsanordnung to avoid overflows in an adaptive, recursive wellendigitalfilter with festkommaarithmetik.

摘要

A method for avoiding overflows in an adaptive recursive digital wave filter consisting of a transfer filter (ÜF1) and a gradient filter (GF1), transfer filter and gradient filter in each case exhibiting an adaptor (AÜ1, AG1) with given coefficents ( mu ), in which the signal output by the transfer filter to the gradient filter is multiplied by a scaling factor (S) which is equal to the difference between 1 and the amount of the given coefficient. …IMAGE…
