Abstract

When signals on a transmission line are divided two ways at a junction of three transmission lines multiple reflection waves will occur from impedance mismatching. This results in waveform distortions an increase in the effective risetime of input pulses and false triggering in high speed logical circuits. A transmission line network with a resistively matched 3port at a junction is discussed as a circuit which will furnish output waveforms similar within given tolerances to the waveform of the input. As transmission lines of unequal length are used here the network transfer functions include three different variables. However expansions of network transfer functions are presented with respect to the three variables. This enables us to calculate output responses. :i:
