Abstract

The invention can be used in signal recognition systems and data transmission systems as a simultaneous frequency analyzer of high-speed signal conversion devices. The purpose of the invention is to increase the functionality achieved by reducing the attenuation of signals in the converter. The converter is made in the form of a long line consisting of a ferrite plate 1 with a single-layer winding 2, a dielectric plate 3, a plate 4 of resistive material, metal electrodes 5, 6 and 7, which are provided with plates 3 and 4, a ferrite plate 8 equipped with winding 9. The electrodes 5 and 6 and 6 and 7 pair in pairs form the sensors of the in-phase and quadrature frequency-dependent components of the signal, corresponding to their coordinate, and are the outputs of the converter. The impedance of the two-port 10 is chosen equal to the output resistance of the long line. Signal (Л 1eospdkher рС 7 S 3/2 3 If 5 рС 7 S 3 00 el 00

The invention relates to radio engineering and radio communications technology and can be used in signal recognition systems and in data transmission systems as a simultaneous high-speed frequency analyzer, signal conversion device.

The purpose of the invention is to increase the functionality of the converter.

In the drawing, a frequency-coordinate converter is represented.

The frequency-coordinate converter is made in the form of a long line consisting of a ferrite plate 1 equipped with a single-layer winding 2, a dielectric plate 3, a plate 4 of a resistive material, metal electrodes 5-7, which are provided with a dielectric plate 3 and the plate 4 of a resistive material, ferrite plate 8, provided with a winding 9 and two-port 10.

The electrodes 5-6 and 6-7, in pairs, form sensors of the in-phase and quadrature frequency-dependent components of the signal, their respective coordinates and are the outputs of the converter. The ne; ends of windings 2 and 9 form the input of the converter, and the second ends of windings 2 and 9 are connected by means of a two-terminal circuit 10 whose complex resistance is equal to the output resistance of the long line.

The device works as follows.

with along it, at the same time, in different sections between the corresponding pairs of metal electrodes 5-6 and 6 7, potentialon differences arise, which form you, and frequency-dependent signals corresponding to the coordinate of the electrodes. When the frequency of the input signal is changed, the max-value of the transverse current, recorded by the sensors, moves along the line.

The invention also makes it possible to reduce the attenuation of a signal in a converter.
