Question 4 was marked.
For A(k) one mark was given for each correct answer in the DFT.
For part (b), I assumed (apparently incorrectly) that you would show how you had computed your answer. So I asked Mike to assign one mark for each correct value of W^k and 1 mark for each correct final answer. Unfortunately, many of you either did not show how you arrived at your answers or did not give the values of W^k.
The total was out of 12.
The abbreviation "wts?" means "weights" and means you didn't give the values of W^k.
If you have a problem with the marking scheme above then see me. If you don't think you were marked according to the instructions above then hand your assignment back to Mike with an explanation.
