The invention relates to automation and numerical engineering and can be used in electric stoving systems. : j automatic logging (following radiolocation and navigation, radio communication equipment, in automatic frequency control systems, etc.), as well as in measuring equipment for creating astatism and automatic search with output voltage applied.

A device is known for automatically maintaining the in-phase electroacoustic oscillations of two independent generators, in which the dependence of the static error on the external error f 1} is completely eliminated by using the integral dependence of the oscillation phase on their frequency.

The disadvantage of it is the lack of memorization of the output noise during a pause in the input signal.

The closest technical solution to this is the integrator, which solves the problem of storing the output signal during the pauses in the input signal (sj

However, the use of such integrators in analog systems requires the presence of analog-digital and digital-analog converters, which complicates the integrator and reduces its accuracy.

The purpose of the invention is to increase the stability of the output signal in the absence of an input signal and simplify the integrator.

To achieve the goal, a voltage integrator comprising a pulse generator, a phase difference meter and a phase difference to voltage converter, input

The oscillator 1 and the pulse shaper 2 at its output are intended to create two pulse sequences. The frequency of the first one is fixed and determined by divider 3, and the frequency of the second is controlled by the input voltage of the integrator using the voltage converter 4 and the duty cycle of the pulses from the pulse generator 2 through the divider E. The converter 4 controls the duration of the strobes, i.e. the number of pulses in packets at the output of the gating pulse shaper 6, The average frequency of the second pulse sequence is determined by the average duty cycle of the pulses at the output of transmitter 4 at zero input voltage, as well as by the divider at the output of the gating pulse shaper 8 and the measuring torus O phase difference the voltage provides for the separation of the phase difference of these two pulse sequences. The output terminal of the converter 9 represents the integral of the input due to the integral dependent phase of the second pulse sequence from the input terminal. Since both sequences are formed from the voltage of a generator 1 common to them, their mutual instability is absent, which ensures that water is remembered in the proposed generator. Automatic search frequency, i.e. the beat frequency at the output of prv8 O4 of the explorer 9, is determined by the release of the initial detuning of the average frequency of the controlled impulse sequence relative to a fixed, i.e. Choosing the coefficients of the dividers 3 and 7. The application of the proposed integrator will expand the range of application of the prototype, since, compared with it, it has a new useful property of recalling the output voltage. The use of the proposed replacement integrator will give an economic effect, which means that with the same quantization accuracy, the input voltage input, for example, p, SUD uses 2-3 times (times less than digital microcircuits) by eliminating the need for additional Devices that provide automatic search and stop.
