In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based on the LM386 IC from National Semiconductor. The audio amplifier will be a self-contained, battery-operated component. In the second part of the lab you will construct a microphone circuit using a compact electret condenser microphone cartridge.
