The Application of Matrices to Vacuum-Tube Circuits

The matrix equations for the triode in the grounded-cathode, grounded-plate, and grounded-grid connections are derived for linear operation. The nonbilateral characteristics of the networks are pointed out, and a table relating matrix elements is calculated on this basis. The formula for the gain of an amplifier is derived for one stage and then for m identical stages. Two examples are given which illustrate the advantages of the matrix method.
