Title:
ADAPTIVE NONCYCLICAL DIGITAL FILTER
Document Type and Number:
Japanese Patent JP3300087
Kind Code:
B2
Abstract:
PURPOSE: To remove limit defects of an application area by providing a filter and a control units for sampling an input and a reference signals at an improved sampling rate, and another filter unit which operates at a prescribed rate.
CONSTITUTION: This filter has a filter unit F1 having a filter coefficient W, capable of controlling N (number of output side) and the control unit CU for controlling the coefficient W. Sampling is performed under a sampling rate fm properly improved by the units F1 and CU, while having a delay in which the input signal Xk and the reference signal dk successively and cyclically change. Then, this filter has another filter unit F2, having the coefficient W of a filter, capable of controlling N which operates under the prescribed sampling rate fk and capable of controlling N. Thus, defects in control of an application area resulting from an insufficient convergence in filters operate according to the minimum mean square algorithm and the assumption of a stable statistical random signal or the like.
