FIELD: computer engineering. SUBSTANCE: device has input terminal 1, function generator 2, analog memory units 3-5, integrators 6-8, comparators 9-11, reference voltage source 12, univibrators 13-15, 20, D flip-flops 16-18, rectangular pulse generators 19, 28, 32, counters 21, 29, 33, digital memory units 22 and 23, decoder 24, commutator 25, flip-flop 26, pulse distributor 27, divider 30, indicator 31. Device provides possibility to calculate function of initial moments, dependency of moments on their order or random argument as well as arbitrary function of random order. EFFECT: increased functional capabilities due to possibility to calculate function of moments of random processes, decreased time for calculation of k-order moments by factor of k due to simultaneous detection of these moments in single measurement, increased precision of calculation when non-stationary processes are investigated. 3 cl, 2 dwg
