Patent EP-0400850-A3 (EP)
IPC: H03H21/00
Filed: 1990-05-18
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.
