Question: The output stage on an amplifier in an old radio is to be matched to the impedance of a speaker as shown in Figure P8.56.

The output stage on an amplifier in an old radio is to be matched to the impedance of a speaker as shown in Figure P8.56. If the impedance of the speaker is 8 ohms and the amplifier requires a load impedance of 3.2 K ohms determine the turns ratio of the ideal transformer.
