Please provide the Matlab code for the following 2.1 filter, conv, fft Generate an impulse and some arbitrary non-recursive filter impulse response (IR): The impulse has a length of 201 samples and is (temporally) centered in the middle The filter IR has a length of 40 samples (e.g., you can use a Hann window) useful commands: zeros, hann Now filter you impulse with your IR in different ways: Use the conv function of MATLAB Use the filter function of MATLAB Do a point-wise multiplication of the Fourier transforms of the impulse and the IR with a length of 201 Do a point-wise multiplication of the Fourier transforms of the impulse and the IR with a length of 201+40-1 240 Useful commands: conv, filter, fft Now shift your impulse in time and observe how the result of the filtering changes. Observe especially what happens once the impulse is getting close to the boundaries of the IR (useful command: circshift). How do you explain what happens?
