Download and install the latest versions of MATLAB and MultiSim fromhttp://software.udayton.edu2. Design the summing audio amplifier circuit depicted in Figure 1 using operationalamplifiers (op-amps). Note that the gain required for the microphone/message signal isapproximately a  100 and the input impedance of the microphone input should not beless than 1k . We require the DC input voltage A to be equal to  6V to ensure that theoutput signal am(t)  A does not drop below 0 volts (i.e., am t A ( ) 0   ). Your designmay include more than one op-amp stage.Figure 1: Summing Audio AmplifierImplement and simulate/verify the functionality of your design (summing audio amplifiercircuit) using NI Multisim. Use LF353 op-amps. Use a sinusoidal signal generator tomimic the input/audio signal from the microphone (20-30 mV @ 10 Khz) and a DCvoltage source of your choosing for A.
