Arrangement having a non-recursive filter. |
摘要 |
Means for weighting a sequence of delayed versions of the input signal in accordance with a sequence of coefficients which are each adjusted iteratively by positive and negative correction steps, respectively, with variable step-sizes, the step-size parameter being selected for each iteration and for each coefficient by means of a run-length detector to which the sign of each correction step is applied and which selects a larger or a smaller step-size parameter depending on the number of correction steps having the same sign and preceding the relevant iteration. Use: echo canceller, equalizer.
