a) Determine the backward differences y1[n] and y2[n], respectively,
of the signals and plot the signals and their backward differences. How do y1[n] and y2[n] compare to each other?

b) Determine the backward difference y3[n] of the signal and plot x3[n] and y3[n]. How does y3[n] differ from y1[n]?

c) Calculate the accumulation and plot it. Which of the three signals
x1[n], x2[n], or x3[n] does it match?
