    Actually I and Asad Hameed are working on the same thing. So in particular the last question he asked you and I guess you forgot answering him: 

    "Kindly explain the term in the denominator: "FFT\_STAGES-1".  Does it come out to be 1/16 as mentioned in your previous post?."

    Can you please answer it?

    Hi,

    Please try the following and get back to me so we can sort it out:

    1) Run the matlab script found here: <c2000ware>\libraries\dsp\FixedPoint\c28\examples\FixedPoint_RFFT\matlab\ with the inputs that you have,

    2) Compare the output with your output from running the code on F280025.
