Use MATLAB to perform the following: 1) Record your voice for 2 seconds 2) Play and plot your recorded voice in time-domain 3) Take Fourier Transform of your voice 4) Plot your voice in frequency-domain 5) Create noise (high frequency noise) with multiple frequencies x(t) = a₁ cos(w₁t) + a₂ cos(w₂t) + a3 cos(w3t) 6) Add the noise to your voice 7) Play & plot voice + noise in time-domain 8) Take Fourier Transform of voice + noise & plot signal in frequency-domain 9) Add a filter to suppress the noise 10) Play & plot filtered signal in time-domain 11) Take Fourier Transform of the filtered signal & plot it in frequency-domain
