Q1. Design an audio amplification system to be used with an Arduino microcontroller. The output of your system should not be inverted (amplification without inversion) and should have a maximum of 5V suitable for the Arduino. Assume the maximum input voltage is 20mV.
a. Performthecalculationstodeterminethecomponentsandtheirspecifications required to implement the design.
b. Develop a Proteus Simulation model to test and verify your calculations.
c. Submit a list of components you will require to implement the design on a
breadboard.
NB: Consider standard resistor values for your final design. Also consider the effect the use of standard values will have on the gain of your system given the 5V maximum voltage.

Q2. Import an audio signal into MATLAB (from any preferred source) and observe the effect on the audio signal when added noise is added to the signal. Repeat the test with noise at different levels. Report your observation.
