the inputs of the corresponding key pair, the remaining input of one of which, and the third input of the key included at the input of the first integrator, are connected to the output of the calibrator of pulses.

FIG. 1 is a block diagram of a functional converter; in fig. 2 shows timing diagrams for the operation of the circuit.

In the proposed arrangement, the voltage L. is connected to the input of integrator 1 and through keys 2 and 3 to the inputs of integrators 4 and 5. The output of integrator 1 is connected to the input of comparator 6, the output of which is connected to keys 2 and 8 via shaper 7. The outputs of the integrators 4 and 5 through the zero-organs 9 and 10 and the trigger 11 is connected to the keys 2, 3, 12, 13 and to the pulse distributor 14. The output of the distributor

14 is connected to a source of reference voltages 15 and keys 2, 3, 8. Source outputs

support voltages of the subkey to the keys

12, 13 and through key 8 - to the entrance and integrator a 1.

The proposed device works as follows.

The terminal Lv is fed to the input of the integrator 1 and to the inputs of the private keys 2 and 3. Pa the output of the integrator 1, depending on

The input and output interface U, appears

increasing voltage (see Fig. 2). When it is reached by output integrator of the integrator of the response level of the complexer 6, the last one is activated and the shaper 7 of the calibrated pulses is triggered. At the output of the calibrated pulse generator, a pulse with a duration / o appears. This impulse opens the key 2n. The voltage Ix is connected to the integrator 4. A zero voltage is maintained at the output of the integrator 5. The voltage Ux is integrated by the integrator 4 over time / o- After the time / o keys 8, 3, 12 are opened and the key 2 is closed, the second input of the integrator 1 is supplied with the voltage Lo, opposite with the voltage Ux from the source of the reference voltages 15 The voltage t / oi from the source of the reference voltages is applied to the input of the integrator 4 through a switch 12 n at its output, the voltage decreases. The voltage U is applied to the input of the integrator 5 via the switch 3 and the voltage increases at its output. After time / d., When the voltage at the output of the integrator 4 reaches zero, the zero-organ 9 is triggered and through the trigger 11 closes the keys 3 and 12, opens the electrical circuit 2 and 13 and through the distributor 14 connects to the output of the reference voltage source 15 voltage t / 02. At the same time, the input of the integrator 5 through the switch 13 is supplied with voltage to discharge the capacitor of the integrator 5 to the bullet level, and through the switch 2 the voltage is applied to the input of the integrator 4. When the output voltage of the integrator 5 reaches zero, the zero-organ 10 is triggered and trigger 11 closes keys 2 and 13, opening x — where GO UorUr, ... U, Equation (3) can also be represented as: a, - j ajU {- J Thus, the proposed functional instructor allows to obtain a time interval, proportional to the power polynomial, or frequency, inverse proportional to the degree polynomial, has great speed, high precision and greatly simplified in comparison with known circuits. It should also indicate the great functionality of the proposed functional converter. So, if the discharge of the capacitor of the integrator 1 is performed only for a time tx or tx or tx /, then the output time interval can be

em key 3 n 12, and through the distributor 14 connects the output of the source of the reference capacitance 15 to the voltage I.

In the future, the work of integrators 4 and 5 is similar to that described above, the number of integration cycles depends on the required functional dependency and is set by the program in the distributor 14. During the time "
