As an Engineer, you are required to design a two-stage audio preamplifier. The preamplifier will have a microphone input and its output will drive a power amplifier which will supply maximum of 6W to speaker. For the purpose of this project, you are only required to design a two-stage audio voltage preamplifier with the following requirements. Input signal range 20mV to 50mV - Minimum range of gain adjustments from 80 to 180 A maximum output signal swing should be obtained such that later a power amplifier is interfaced to provide maximum power to the speaker.
