EE 541 USC Viterbi School of Engineering J. Choma Homework #02 13 Fall Semester, 2011 U niversity of S outhern C alifornia USC Viterbi School of Engineering Ming Hsieh Department of Electrical Engineering EE 541: Homework Assignment #02 Fall, 2011 Due: 09/08/2011 Choma Problem #06: Consider the linear, bilateral, and symmetric two-port network abstracted in Figure (P6a). Observe that the load (R l ) terminating the output port of the network is purely resistive, as is the intrinsic impedance (R s ) associated with the applied signal source. Linear, Bilateral, Symmetric Two-Port Network I 2 V 2 V 1 R l R s V s I 1 Z in Figure (P6a) (a). In terms of the open circuit impedance parameters, z ij , of the subject network, show that maximum power transfer between the applied signal source and the network input port requires  2 11 s 11 l 12 zR z .  (b). What network condition must be satisfied if the indicated input impedance, Z in is designed to be KR l , where K is a positive, frequency invariant constant? (c). If Z in = R and R l = R , what relationship must resistance R satisfy in terms of the open circuit impedance parameters of the linear, bilateral, symmetric two-port network?
