a= 1 b= 4 c= 2 d= 4 Discrete cosine transform

a= 1 b= 4 c= 2 d= 4

Discrete cosine transform (DCT) is an important DSP tools to compress an image signal. Based on the signal, x(n} = {1+a, 2+b, 3+c, 4+d}, where a, b, c and d are the last four digits of your matric number (O digit also can be used); (i)Compute the DCT transform of the above, x(n). (ii) Reconstruct the original signal. Osk
