DIGITAL INTELLIGENT MULTISTAGE FILTER Russian patent published in 2011 - IPC H03H17/00 

FIELD: information technology.

SUBSTANCE: digital intelligent recursive filter, having first, second, third, fourth, fifth and sixth matrix function forming units, first, second and third correction units, first, second and third differentiating units, first, second and third summation units, first, second and third delay lines, a unit for generating and outputting prior data, first and second regularisation parameter calculation units, additional units: seventh and eighth matrix function forming units, fourth correction unit, fourth differentiating unit, fourth summation unit, fourth delay line, third regularisation parameter calculation unit, as well as connection thereof with the rest of the units. The main idea lies in calculation and successive refinement of the regularisation parameter value, which enables to increase accuracy of estimates of the information process.

EFFECT: high accuracy of estimating parameters of an information process in measuring systems.
