Suppose that each output channel of a computer's sound card can be represented by a 1-V ac source in series with a 32Ω resistor. Each channel of the amplifier in the external speakers has an input resistance of 20 k, and must deliver 5 Ω into an 8Ω speaker.

(a) What are the voltage gain, current gain, and power gain required of the amplifier?

(b) What would be a reasonable dc power supply voltage for this amplifier?
