Question

Write a program in MATLAB to compute the 1-dimensional discrete cosine
transform (1D - DCT) of a signal.

Answer 1

Answer #1

Directly MATLAB function is there we can use that function.

The function is

Y= dct(X) ; it will give discrete cosine transform of X and it will be stored in Y. Here the size of both X and Y are same.

(or)

Y= dct(X,N) ; it will give dct of X and it will be stored in Y. Here the size Y is truncated to N before transforming.
