【発明の名称】ディジタルフィルタに使用するための係数を生成するためのシステム
Document Type and Number:
Japanese Patent JP3250801
Kind Code:
B2
Abstract:
There is disclosed a system and method for generating coefficients for use in a digital filter. The coefficients are generated utilizing an iterative adaptive process employing a least mean square process wherein the filter coefficients are updated by an amount during each iteration dependant upon the stochastic average of the gradients generated during prior iterations. The response of a filter standard to an applied input signal is combined with a response of the adaptive filter coefficients to generate, during each iteration, an error signal. If the error signal is less than a predetermined standard, the iterative process is stopped, and the last used filter coefficients are utilized as the final filter coefficients of the digital filter.
