3. You are to design a microphone pre-amplifier that passes frequencies between 30HZ and 1.2kHz. At the center frequency (fo) the gain of the amplifier is to be 40 dB's. Design the amplifier according to the specifications listed above. Note that a power supply is available to power the pre-amp. Determine suitable values for the system components to meet the design specifications. Build and generate a Bode plot of your results. Measure the center frequency and half-power frequencies of your pre-amp and compare with specifications. Comment on the results and be sure to include a schematic of your circuit and Bode plot.
