Consider the following sequence of values:

10	11	12	11	12	13	12	11
10	-10	8	-7	8	-8	7	-7

(a) Transform each row separately using an eight-point DCT. Plot the resulting 16 transform coefficients.

(b) Combine all 16 numbers into a single vector and transform it using a 16-point DCT. Plot the 16 transform coefficients.

(c) Compare the results of (a) and (b). For this particular case would you suggest a block size of 8 or 16 for greater compression? Justify your answer.
