FIELD: radio engineering; measurement equipment.
SUBSTANCE: invention relates to radio engineering and measurement technology. Technical result is achieved due to digital meter for statistical characteristics of random signals, which contains analog-to-digital converter, register, digital filter, mean value calculation channel, the first and second quadratic converters, mid-square shaping channel, subtracter and clock generator, medium value and mean square generating channels comprise n samplers each containing adder and shift register of multi-bit codes.
EFFECT: technical result is to provide continuous digital measurement of mean value and variance of random signals with high accuracy with minimum number of necessary arithmetic operations.
