Abstract: FIELD: measurement technology. 
     SUBSTANCE: proposed converter depends for its operation on bubble domains and microelectronic technology. Use is made of uniaxial ferromagnetic disk covered with domain advancing structures, as well as of bubble generator and annihilator. Revolving magnetic field produced by mentioned disk sets bubble domains in motion over domain advancing structure concentrically with respect to shaft. Rigidly coupled with shaft is second bubble domain detector, and first detector is fixed in zero position of shaft. When bubble domain is moving near detectors, the latter generate current pulses. Time of bubble domain movement between detectors determines shaft angular position φ. Time t is evaluated by filling counter with generator clock pulses during period between output pulses of bubble domain detectors. Shaft angular velocity ω is found by measuring angle φ pre  within one turn of bubble domain and angle φ post  within next turn of bubble domain, finding difference between these angles, and dividing it by time taken for one revolution of bubble domain (constant value). Constant value of 1/T can be taken as 1 or 10 n , where n is integer number. Then angular velocity can be determined as difference between two sequential measurements of angle. Subtraction is made using reversing counter. Shaft angular velocity ε is found from difference between two sequential measurements of shaft angular velocity divided by time T. First measurement of ω is made by first reversing counter and second one, by second reversing counter. Difference in angular velocities is found by subtracter that yields angular acceleration at its output. 
     EFFECT: enhanced precision, reduced size, facilitated signal processing.
