1.49 A designer has available voltage amplifiers with an input resistance of 10 k, an output resistance of 1 k, and an open-circuit voltage gain of 10. The signal source has a 10-k resistance and provides a 5-mV rms signal, and it is required to provide a signal of at least 3 V rms to a 200- load. How many amplifier stages are required? What is the output voltage actually obtained?
