This invention relates to analog computing technology.

A known transducer containing a polytron-type electron beam tube, the functional plates of which are connected to analog storage devices, the collector is connected to the inputs of the adder, an intermediate function generator connected between the transducer input and the polytron control tube Til.

The disadvantage of the device is low accuracy, due to the uniform arrangement of nodes, interpolation.

The closest technical solution to the proposed is a functional converter containing first and second polycron tubes such as polytron, first and second blocks of analog storage devices, the outputs of which are connected respectively to their functional plates of polytron type first and second electropneumatic tubes that control the first electron beam tube The type of polyrun is the input to the L2j converter.

The disadvantage of such a converter is the impossibility of automatically learning the type of functional transformation on the reference function, which limits its scope.

The purpose of the invention is to expand the field of application of the converter due to the automatic learning

0 type of functional transformation.

The goal is achieved by the fact that a functional converter containing first and second polycron tubes such as the first and second blocks of analog storage elements, the outputs of which are connected respectively to the functional plates of the first and second electrolux tubes of the polytron type,

the control input of the first electron tube of the polytron type is the converter input, additionally contains n discriminators of the input voltage interval, parallel keys, 2n single-pole operation mode switches, a dividing unit, each analog storage element of the first and second blocks of analog storage elements

0 performed on the integrator, outputs

discriminators interval. the input voltage is connected to the control inputs of the corresponding analog switches and through the corresponding transducers of the operating mode with the inputs of the integrators of the first block of analog memory elements, the information inputs of the analog switches. They are combined and are the input of the function type of the ego conversion, the output of the analog J and J via the corresponding operation mode switches, they are connected to the inputs of the integrators of the second block of the aforementioned 5x memory elements, which controls the input of the first electrically received Polytron-type logging is connected to the control input of the second Nitro-type electron tube and the discriminators of the interval; the input voltage, the collector outputs of the first and Polytron-type tube, respectively, are connected to the inputs of the divider and the divisible block of the division l whose input is the output of the converter / moving contacts of single-pole operation mode switches mechanically integrated

The drawing shows the block diagram of the functional Converter.

The converter contains the first and second electron-beam tubes of the type of polytrope 1 and 2, the first and second blocks 3 and 4 of the analog fuses, which are made on the integrators 5,, ..., 5 ,,, and b, ... 6 ", ndcr" 1 "of the input voltage interval 1 ,,.,., 7, n analogue switches 8. ,,,, 2p single-pole switches of the operating mode 9,. . block to deluvie.

The converter works in the following way.

In the learning mode, the functional oversight, which allows to obtain a signal from (t) and, (t), is not necessary to be set for Exit GX on this functional converter so that the Hfoi works in the functional mode A converter, when applied to the control unit, the inputs of polyples 1 and 2 input voltages U, (t) from the output of the converter were removed voltage U5, (t) "H CWx (t).

In the learning mode, all the contacts of the operation mode switches 9, ..., 92 are closed. Signals 1C (t) are removed from the outputs of the analog switches 8 ..., 8u, the duration of which at the 1st output corresponds to the time the voltage Ux (t) is in the –th amplitude interval, the piece of analog terminals is controlled by the voltages (t "Ka & ylmk from the outputs of the discriminators of input voltage intervals 7, ..., 7". Simulators simultaneously (t) are fed to integrators 5, ..., 5p, the outputs of which form signals proportional to the duration of the voltage llx (t) in the} -th amplitude interval.

From the outputs of the analog keys 8,. .., 8 "signals" arrive at - integrators 6 ..., 6f, at the outputs of which signals are generated that are proportional to the integral of Uyj (t) over a period, i.e. iUyy (t) dt. If further to form a private

It is known that with an increase in the analysis time &

Thus, in the proposed

A 5 converter converter is the acquisition of signals at the outputs of the integrators 5,:. ., 5y, and 6 ,. .., 6 „for a fairly long analysis time. In the function conversion mode, the contacts of the switches 9, ..., 9 are opened. The input signal is fed to the control inputs of polytrons 1 and 2, from the collector outputs of which the voltage is taken off with automatic investment and li (t). At the output of dividing unit 10 a quotient is formed.
