Hi I am currently studying FHT Algorithm but have a hard time to grasp it.
I want to calculate FHT when N=8.
thanks to (19) of the upper link, the FFT can be written as below
as T and H have inverse matrix, using associative law is allowed
then for N=8,
I have used the final expression to my wave example, but did not gain proper result.
that indicates there must be something wrong.
but don`t know where is the error.
anyone knows what is the wrong in above?
