A. Create the following three discrete-time signals, assuming a time range of [0,12] x = a box of height 1 starting at time n=2 and ending at n=8 h1 = a pulse of length 4 & height 1 starting at time 0 h2 = 1 at n=0, -1 at n=1, and 0 otherwise B. Use numpy.convolve() function to find y1=x*h1 and y2=x*h2 (where * indicates convolution, not multiplication). C. Create a time vectors nx, nyl and ny2 for plotting x, y1 and y2. Use the stem plotting function to plot the signals on a 3x1 subplot, using a y-axis between -2 and 5 and a time axis from 0 to 20. Label and title the graphs. Verify that the signals for (yl) and (y2) match what you expect from your prelab. Report discussion: The systems corresponding to impulse responses h₁ [n] and h₂[n] capture different information about a signal. Comment on what aspects of the input signal correspond to the largest values of yı[n] and y₂[n].
