Consider the following signal: 𝑥[𝑛] = {−1,0,1,2,3,4} , 0 ≤ 𝑛 ≤ 5.

1. Plot the signal 𝑥[𝑛].

2. Write a complete code to flip (fold) the signal 𝑥[𝑛] with respect to y-axis (vertical axis) so that we obtain 𝑥[−𝑛].

3. Add the original signal to the flipped signal, that is: 𝑥[𝑛] + 𝑥[−𝑛] and plot them in the same plot; the resultant plot should have even symmetry. 4. Subtract the flipped signal from the original signal, that is: 𝑥[𝑛] − 𝑥[−𝑛] and plot them in the same plot; the resultant plot should have odd symmetry.

Hint: use the MATLAB function fliplr to flip the signal with respect to y-axis (vertical axis).

As this clearly looks like a homework assignment, show us what have you attempted yet.

After thatm we can come back to help you addressing this question. I'm serious.
