SU360620A1 - METHOD FOR DETERMINING THE OWN FREQUENCY OF CALCULATED GALVANOMETRIC FUNCTIONAL CONVERTERS - Google Patents

Description

The invention relates to the field of electrical electrical devices and can be used. Nip 1 production of galvanized acoustic transducers.

To determine the frequency of our own frequency, the use of talvanometry of the bskie shreobrlzovateley. Use the method of Sherin.ga., According to the "1H | y | frequency" O | Prei: I’m yT | By the maximum of 1H | However, such a method for determining the C0: b1st1vek1nogo frequency in the production of sLo | vy xVLI trues (deem1koy and inconvenient, and so the frequency depends on the degree and comfort.

The purpose of the invention is to immobilize and determine the potential of the nipeobenzal and automatic power supply.

This is achieved by the fact that the input of the Converter is supplied from one generator to the sinusoidal sigial at the frequency, and the high voltage output of the converter (to the oscillograph of the receiver). natural frequency and discontinuous.

It is known that a galvanic metric. A fundamental func- tional-to-digital converter is a hygienic testing device, with a KOTCipoiro movable part fastened, on an example | p, sensor e. d. Hall-If the sensor is e. d. Hall in practically applicable frequency range

Consequently, the component is dependent on the angle φ of the transmitter’s cumulative condition, and the angle φ depends on the ratio between the running frequency and the natural frequency of the converter and on the degree of w r.
