A method has been developed for the synthesis of bridge sensors and alternating current meters used in information - measuring and control systems with antenna matching devices of radio stations of various ranges. The method consists in determining the equations of zero and the mathematical conditions for the implementation of the sensor or meter, according to which the electrical circuit of the device is developed and is based on the analysis of vector diagrams of voltages and currents of a four - arm resistive AC bridge. The circuits of such devices synthesized by this method are structurally easier to implement in a wider frequency range, it is easier to process information in them at an intermediate frequency, as a result of which, they are more noise-resistant and have a smaller error. A universal circuit is presented, in which selective meters and sensors are implemented on the basis of a resistive bridge, the theory of which is considered in the article.
