The operation is dedicated to application of the tensor methodology of. Top to the analysis of electrical key diagrams of stages of an electronic equipment. As an example the tensor method of the analysis of a transistor frequency transformer (FT) of a superheterodyne radio receiver with a frequency-selective load by the way of double-loop bandpass filter (DBF) surveyed. The basic virtues of application of the tensor methodology to the analysis of electrical key diagrams are formulated, to number which one can be considered following: introducing of model of a primitive web of a calculated stage, as generalized frame (F), defining dimension of discrete space - structure of electric circuits for all possible(probable) variants of build-up of a key diagram; propagation of results of calculation in a primitive web on composite electric circuits (as projections of this primitive web in quotients F); combination in a uniform analytical problem of a network architecture and processes, flowing past in her, (share usage of Ohm's laws and Kirchhoff); the considerable lowering of volumes of evaluations and convenience of their introducing on a computer, that in turn promotes a heightening of efficiency of calculations specially in accordance with thickening the calculated circuits. For a functional test of a method the analytical simulation for a stage a FT with DBF of the receiver of a radio set of a range МW-DМW is conducted on the basis of the classic approach in a medium of mathematical simulation MathCAD and on the basis of the tensor methodology in a mathematical medium Maple 8. The simulation has confirmed realizability of a tensor method of the analysis, and also reliability of obtained results by their precise concurrence to classic expressions and correspondence of character of dependences to a well-known aspect. The designed method can be useful at a stage of projection and calculation of elements of radio devices.
