Discrete Hartley Transform when N=8












0














Hi I am currently studying FHT Algorithm but have a hard time to grasp it.



I want to calculate FHT when N=8.



http://mathworld.wolfram.com/HartleyTransform.html



thanks to (19) of the upper link, the FFT can be written as below



enter image description here



as T and H have inverse matrix, using associative law is allowed



enter image description here



then for N=8,



enter image description here



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?
