Note on the Use of Tchebycheff Functions in Dealing with Iterated Networks

Expressions for the transmission matrices of four-terminal networks in terms of Tchebycheff functions have been given previously. Here, relations among these functions are used to give a convenient formula for the voltage gain of such networks; the transfer impedance etc., could be handled similarly. As an example, the low-pass network formed by cascading inductance-capacitance T sections is discussed.
