ADAPTIVE DIGITAL PREDICTOR Russian patent published in 2012 - IPC G06F15/00 

FIELD: information technology.

SUBSTANCE: first input of an XOR element is connected to the sign bit output of the adder of the first subunit for calculating the second derivative, and the second input is connected to the sign bit output the second adder of the second subunit for calculating the second derivative; the output of the XOR element is connected to the first input of a second AND element and through an inverter to the first input of a first AND element, and second inputs of both AND elements are connected to the bus of the output ("g") of the shift register of unit for clocking the prediction unit; the output of the first AND element is connected to the set line of a flip-flop, and the output of the second AND element is connected to the zero input of the flip-flop; the true ("1") output of the latter is connected to the address input of a multiplexer, whose input buses are connected to outputs of the quadratic and linear prediction subunits; the output of the multiplexer of the adaptation unit is the first data output of the device.

EFFECT: broader functional capabilities owing to use of an adaptation unit having an XOR element, an inverter, a first and a second AND element, a flip-flop and a multiplexer.
