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

FIELD: information technology.

SUBSTANCE: digital predicting and differentiating device includes a unit for estimating first derivatives, having a subunit for calculating a first derivative at a second (n-1)-th reference point of process history consisting of three adders, the output of which is the third data output of the device, and a subunit for calculating a first derivative at the third (n-2)-th reference point of the process history consisting of three adders and a block of inverters, the output of the subunit being the fourth data output of the device.

EFFECT: broader functional capabilities of prediction devices by obtaining estimations of first derivatives using numerical differentiation formulae for prehistory nodes of an input smoothed discrete sequence.
