A Treatment of Cascaded Active Four-Terminal Networks, with Application to Transistor Circuits

A formula previously given for the transmission matrix of
n
identical passive four-terminal networks connected in cascade, in terms of the modified Tchebycheff functions of the second kind, is extended to active networks. The formula is found to differ chiefly in that the determinant of the matrix (which is now not identically unity), enters explicitly into it. Applications to cascaded transistor circuits are discussed.
