Tensor analysis of multielectrode-tube circuits

The method of tensors, as applied to the analysis of electrical systems, has gained favor because of its versatility. The most common application of the method in electrical engineering is the analysis of the dynamics of rotating machinery, but a further application is presented in this paper. The attack includes flexible analyses of the characteristics of triodes, tetrodes, and pentodes, and their use as amplifiers, oscillators, and modulators.
