I am practicing rfft using EVM56807. I know the output is pZ, however, the question is how to get Real Part and Imag Part to calculate PSD. Furthermore, if showing the result by PCmaster, considering data transmition rate, what' s the largest samples can be done by continuous rfft? Any help would be appreciated! David

Good question, If this is possible I would like to know too. I ended up just using the cfft but if I could use the rfft and get both real and imaginary resluts or just the length of the combined vectors that would great. One thing I did notice between the two is that the result of the rfft used the whole array where as the result of the cfft used half the array with the other half containing a mirror of the first half. What is does the acroname PSD stand for (Pseduo Spectral Data)? Jacob  In , "li_xinming" <li_xinming@y...> wrote: > I am practicing rfft using EVM56807.
