    Hi, i am a freshmen in university and would like some help regarding a circuits project.
    I have been given 2 .wav files. One with a clear speech and another with the same speech but with a noise in the background.

    Our project is to isolate the frequency of the noise and design a filter, (low pass, high pass or band pass) using capacitors, resistors and inductors only, to filter out the noise and play the clean speech.

    Software at my disposal is mutlisim as we have not be allowed or trained to use matlab or any other software.
    We can use any software to identify the frequency of the noise.

    Here are the files:
    Speech with noise:
    Clean speech:

    I need to create the filter physically (on a breadboard) and on multisim.

    any help would be appreciated
    Thank you
