write a full report on designing a filtering system for filtration of an input audio sound signal.

nb: choose your own values for the input voltage signals, resistors,capacitor and frequency that will produce not more than 3v of gain and 5v of output voltage signal for the for the filtering systems calculations to reduce the noise and make the audio audible.

nb: add screenshot of proteus simulations for the filtering system with all the calculations in the report.

follow the following steps for the report writing:

1. Objectives

2. Introduction

3. Materials used

4. System design (filtering system with their calculations each (add proteus simulations)

5. Results (with protest simulations)

6. Conclusion

7. References
