Uses a multistage amplifier using a buffer stage,gain stage, and output stage resembling this example:

*D6.91 Amicrophone puts out a peak voltage of 2 mV and has an output resistance of 5 kQ. Design an amplifier system to drive a 24 Ω speaker, producing 0.5 W of signal power. Assume a current gain of B50 for all available transistors. Specify the current and power ratings of the transistors. Buffer stage vi stage stage *D6.91 Amicrophone puts out a peak voltage of 2 mV and has an output resistance of 5 kQ. Design an amplifier system to drive a 24 Ω speaker, producing 0.5 W of signal power. Assume a current gain of B50 for all available transistors. Specify the current and power ratings of the transistors.
