ECE 329 Homework 13 Due: Tue, April 22, 2008, 5PM The following is a set of relatively simple S.C. exercises appropriate for an “exam week”. The following week we will have some more challenging T.L. and S.C. problems to work out. 1. A T.L. with characteristic impedance Z o = 50Ω and length l =0 . 2 λ is terminated with a load Z L = 100Ω . a) Using a S.C., determine (i) the load reFection coe±cient Γ L , (ii) the generalized reFection co- e±cient Γ( d ) at d = l , and (iii) the input impedance Z ( l ) at the generator end. Hand in your S.C. b) Using Z ( l ) from part (a), determine the voltage phasor V ( l ) at the generator end if the generator has an open circuit voltage phasor V T = 10 V and a Thevenin impedance Z T = 50Ω . c) Given the result of (b), determine V + such that V ( d )= V + ( e jβd + Γ L e - jβd ) . d) What is the load voltage phasor V (0) given the result of (c)?
