U tezi se razmatra kriterijum optimalnosti stohastičkog fleš A/D konvertora (SFADC) koji predstavlja osnovu stohastičke digitalne metode merenja (SDMM). Razvijen je matematički i simulacioni model višebitnog SFADC i određen optimum broja bita rezolucije. Napravljen je hardverski prototip 4-bitnog stohastičkog mernog instrumenta (SMI), koji je ispitan brojnim eksperimentima i upoređen sa teorijski određenim vrednostima performansi merenja. Hipoteza ove teze – da postoji optimalni broj bita rezolucije SMI pri kome se ostvaruje maksimalna dobit u preciznosti merenja po ceni dupliranja potrebnog hardvera – potpuno je potvrđena.
The thesis considers the criterion of optimality of the stochastic flash A/D converter (SFADC), which is the basis of the stochastic digital measurement method (SDMM). The mathematical and simulation model of the multibit SFADC was developed and the optimal number of bits of resolution was determined. A hardware prototype of a 4-bit stochastic measuring instrument (SMI) was made, tested in numerous experiments and compared with theoretically determined measurement performance values. The hypothesis of this thesis - that there is an optimal number of SMI resolution bits in which the maximum benefit of the measurement precision is achieved at the price of duplication of the required hardware - is fully confirmed
