CORRELATION MEASURING SYSTEM Russian patent published in 1994 - IPC

FIELD: measuring devices. SUBSTANCE: first and second comparison circuits, pseudorandom voltage generator, flip-flop, equivalence circuit, set of pulse counters and control unit are introduced to accomplish the goal of invention. Control unit has frequency divider, second flip-flop, controlled frequency divider, second pulse counter, code comparison circuit, third pulse counter and memory unit. This implements multiplication based on statistic measure. In addition shift of input signal by value of argument of correlation function is replaced by shift of synchronization pulses of counters in time. EFFECT: simplified design, increased dynamic range of argument of correlation function. 2 cl, 3 dwg
