Problem B.1 Design

Voltage amplifier stages having the characteristics show in the following table are available. The signal source has an open-circuit voltage of 20mV rms and an internal resistance of 2M?. The load is a 20?resistance. Design a cascade amplifier using smallest number of stages that provides at least 1 W to the load. What are the values of the input resistance, the output resistance and the open-circuit voltage gain of your amplifier?
