Let's manually compute y = 2x(−n + 1) using the given sequence x · {−4, 3, 4, 3, −5, 1, −5, −2, −5, 4, 1}: y = 2x(−n + 1)
y(0) = 2x(−(0) + 1) = 2x(1) = 2 × 4 = 8
y(1) = 2x(−(1) + 1) = 2x(0) = 2 × 3 = 6
y(2) = 2x(−(2) + 1) = 2x(−1) = 2 × 4 = 8
y(3) = 2x(−(3) + 1) = 2x(−2) = 2 × 3 = 6
y(4) = 2x(−(4) + 1) = 2x(−3) = 2 × (−5) = −10
y(5) = 2x(−(5) + 1) = 2x(−4) = 2 × 1 = 2
y(6) = 2x(−(6) + 1) = 2x(−5) = 2 × (−5) = -10
y(7) = 2x(−(7) + 1) = 2x(−6) = 2 × (−2) = −4
y(8) = 2x(−(8) + 1) = 2x(−7) = 2 × (−5) = −10
y(9) = 2x(−(9) + 1) = 2x(−8) = 2 × 4 = 8
y(10) = 2x(−(10) + 1) = 2x(−9) = 2 × 1 = 2
I want the matlab code to get the signal sketch!!!
