DIGITAL PREDICTING AND DIFFERENTIATING DEVICE Russian patent published in 2012 - IPC G06G7/12 G06F17/17 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to automatic and computer equipment and can be used to predict stationary and non-stationary random processes, increasing quality and accuracy of control in digital systems for controlling and guiding various objects. The prediction unit includes a first derivative estimation unit. The estimation unit has three subunits for calculating first derivatives. The first subunit, which is meant for the first n-th (current) reference point of the history of the predicted process, consists of one adder. The second subunit, which is meant for the second (n-1)-th history reference point, consists of one adder. The third subunit, which is meant for the third (n-2)-th history reference point, consists of two adders and an inverter unit. Outputs of the subunits are the data outputs of the device.

EFFECT: broader functional capabilities by obtaining first derivative estimates for all equidistant points (nodes) of the two-level history of an input smoothed discrete process.
