The optimum transmission-line pulse transformer

Tapered transmission lines have been found to be useful for pulse-transformer service.1,2 It is the object of this paper to develop a new theory for the optimization of the taper which is based upon the transient rather than the steady-state response of the transmission-line pulse transformer. A criterion for the optimum taper will be established and then applied in a special case in which both ends of the line are nominally matched. Finally, the case of general terminations at both the input and output will be discussed.
