A speech signal with bandwidth of 4 kHz is sampled at 8 kHz. The signal is corrupted by sinusoids with frequencies 1 kH, 2 kHz, and 3 kHz.

1. Design an IIR filter using notch filter components that eliminates these sinusoidal signals.

2. Choose the gain of the filter so that the maximum gain is equal to 1, and plot the log-magnitude response of your filter.

3. Load the handel sound file in MATLAB, and add the preceding three sinusoidal signals to create a corrupted sound signal. Now filter the corrupted sound signal using your filter and comment on its performance.
