DIFFERENTIATING UNIT Russian patent published in 2013 - IPC G06G7/18 

FIELD: measurement equipment.

SUBSTANCE: method is implemented as per the means of high-quality filling of the shaped pulse-width sequences and allocation by means of a reversible pulse counter of pulse difference in adjacent pulse groups, which is the measure of derived physical quantity with further conversion of pulse difference with demodulator 9 to proportional DC voltage. In the proposed device, the information on the derivative is supplied not only in an analogue form as in a prototype, but also in a digital form, which allows using differentiator in digital adjustment and control systems at the information processing stage prior to the processor.

EFFECT: enlarging functional capabilities owing to possibility of receiving the information on a derivative of the varying physical quantity immediately in a digital form.
