Problem. Implement your own Matlab or Python code. Then, fill in the code, plot and discussion part. Libraries related to convolution should not be used and must be implemented based on formulas. rect[n] = [0,0,0,1,1,1,0,0,0),(-451 54), where n is integer r[n] = [0,0.5,1,1.5,2), (0 Sn = 4), where n is integer 1. Define and plot (sketch) rect[k] and r[k] along the k axis (horizontal axis). 2. Plot (sketch) rect[n-k] and r[n-k] along the k axis (horizontal axis)
