The invention relates to automation and computing and can be applied in hardware implementation of functions.

A device is known for erecting a number-pulse code into a quadruple containing two counters, a ruler of drivers, a group of elements AND with a 1-by-1 output circuit assembled according to a binary multiplier circuit with corresponding communications PJ,

The disadvantages of this device are the complexity and significant error of calculations with an even number of bits of counters that are part of a binary multiplier. The closest technical support to the proposed is a device for reproducing a quadratic dependence, containing P-bit summation th counter, ruler (1yr1 rovers, which includes ent drivers, a group of AND schemes, containing en t AND elements with an OR output circuit, a result counter, the input of which is connected to the output of zlemeite OR 2j.

The disadvantage of the prototype is a significant calculation error, which appears with an even number of digits of the summed-down counter,

The purpose of the invention is to increase the accuracy of calculations with an even number of digits of the sum counter.

The goal is achieved -; the fact that the device for reproducing the quadratic dependence, which contains a P-bit counter (an odd number), a group of P / 2 pulse shapers, a group of P / 2 AND elements, an OR element, a result counter, with the outputs of P / 2 lower-order P-bit Dov counter through a group of P / 2 pulse shapers Connected respectively to the first

P / 2 elements AND groups, to the second inputs of which the corresponding outputs (P / 2-l) of the senior bits P of the discharge counter are connected, and 5 outputs P / 2 elements AND groups are connected respectively to the inputs of the OR element, the output of which is connected to the input of the result counter, entered (P / 2 + 1) -th pulse shaper, the input of which is connected to the output

(P / 2 + 1) -th bit of the P-bit counter, and the output of the pulse former is. owls connected to the input element IDN, The drawing shows a block diagram of the S device.

The device for reproducing the quadratic dependence contains a P-bit counter 1, a group 2 of P / 2 pulse shapers, a group 0 3 of P elements AND, a counter 4 of the pulse and an element OR 5,: If P is odd, then the device contains - - drivers , moreover, the outputs from 1 to formers are connected to the corresponding

,, RF inputs and elements, and the output is

the former is connected to the input of the element OR, t, e, with an odd number of bits, the principle of constructing such a 0 te, as in the prototype,

I .. P4-

If P is even, then the W and I-I-j-ro drivers of the formers are connected to the corresponding inputs so that correspond to the elements And, and the output 5 I) of the DR driver connected by the input to the direct trigger output; ra (- | +1) th bit, connected to the input of the element IS1,

The additional introduction of the former allows one to significantly reduce the computational error with an even number of digits P of the totalizer.
