The invention relates to information and measurement technology and is intended to measure the moments (expectations) of random signals.

The aim of the invention is to improve the accuracy of signal analysis.

The block diagram of the device shown in the drawing.

The device contains the first input 1, unit 2 of the transducers value of the inertia (BPZV); the second input 3 of the device, the first switch 4, the memory register 5, the group of elements OR, the counter-decoder 7; the second switch 8, a group of 9 meters, the outputs 10 of the device.

One of the modes of operation of the device is based on the operation of calculating mathematical expectations.

transformed source random signals X. Expression (l) is realized by supplying a source signal with a distribution area W (x) to the input of a binomial converter with a transfer function (2) and calculating the probability of occurrence of output random signals, which are binomial moments.

The system of binomial distributions (2) is obtained by a series-parallel comparison.

0 include, as a special case, the weight functions x previously used in determining the initial moments. This gives additional information about the source signals and

5 greatly expands the functionality of the device.

Analysis of binomial weight functions (2) shows that they allow us to obtain a complete system of binomial moments (their sum is equal to unity). This gives additional information about the properties of the original signals. In the device, it is possible to obtain other more complex moments when using different initial and auxiliary random signals. The operation of the device is based on the operations of serial-parallel conversion of the original signals into random pulsed streams in the BSZV 2, their counting-decryption in the counter-decoder 7 and accumulation of results for many implementations in the counter block 9,

The device works as follows.

The input signal x from input 1 is fed to the input of the BWWD 2. The latter contains the S transducers value - probability. Outputs of this unit with

 by probabilities (5) - (6) are set to single or zero states and through the first switch 4 and a group of 6 elements OR are connected to the inputs of the counter-decoder

5–7, where, in accordance with (4), a parallel counting and decoding of the received single signals is performed. Decoder Counter Outputs

7 are connected via the second switch 8 to the inputs of the first section of group 9 of the counters, where the values of the moments m, are accumulated. The signals from the BVDC 2 through the first switch 4 are also recorded in the first section of the register 5 of the memory and are additionally fed to a group of 6 OR elements. At the next clock cycles on the control pulses from input 3, the AUPR 2 and the first switch 4 are again put into operation. The latter switches the outputs of the AUMV 2 to the inputs f in sequence

the following sections of register 5 of memory, a group of 6 OR elements, a counter-decoder 7, a second switch 8 and a group of 9 counters, which operate similarly to the first section of the above-mentioned blocks. Register 5 of the memory provides storage and submission of the previous information from the BWWS 2 to the countershare 7 when the BWWS 10 2 transitions to the new sections. This ensures the serial-parallel operation of the device.
