rfft output

Started by li_xinming December 6, 2002
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!

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)?
