7.57 The wire that connects an antenna on your roof to the TV set in your den is a 300-2 wire, as shown in Figure P7.57(a). This means that the impedance seen by the connections on your set is 300 s. Your TV, however, has a 75-2 Impedance connection, as shown in Figure P7.57(b). To achieve maximum power transfer from the antenna to the television set, you place an ideal transformer between the antenna and the TV as shown in Figure P7.57(c). What is the turns ratio, N = 1/n, needed to obtain maximum power transfer? 300 2 (a) 75 2 Antenna connections Rear view of television (b) 300 2 n:1 V. antenna 75 2 V, signal D. ell aell
