This is an optional quiz to accommodate those with some excuses. Anyone can take it. The best out of two quizzes will be your Q1 score. 10 8 u 7 8 9 10 1) Express the waveform using the basic signals a) xy(t) = 2r(t + 2) + 3u(t) - 6r(t - 2) + 4r(t - 4) b) xi(t) = 2r(t + 2) + 2r(t) - 4r(t - 2) + 4r(t - 4) c) xi(t) = 2r(t + 2) + 3u(t) - 4r(t - 2) + 4r(t - 4) d) x1(t) = 2r(t + 2) + 3r(t) - 6r(t - 2) + 4r(t - 4) e) None of the above 2) What is the simplified signal? [u(t +1) – uſt - 1)][u(-2t +1) – u(-2t - 4)] a) u(t+1) - u(t -0.5) b) u(t)- u(t-1) c) u(-2t + 1) - u(t-1) d) u(-2t + 1) = u(t + 1) e) None of the above
