Question: 7.47 The input circuit shown in Fig. P7.47 contains two sources, given by i,(t) = 2 cos 103t A, and u,(t) = 8 sin 103t


7.47 The input circuit shown in Fig. P7.47 contains two sources, given by i,(t) = 2 cos 103t A, and u,(t) = 8 sin 103t V. This input circuit is to be connected to a load circuit that provides optimum performance when the impedance Z of the input circuit is purely real. The circuit includes a "matching" element whose type and magnitude should be chosen to realize that condition. What should those attributes be? Matching element 2 :60 20 0.5 mF -Z Load circuit 4 mH DS (1) Figure P7.47: Circuit for Problem 7.47
