real fft get magnitude
I wondered whether this should be in the DSP section but it involves the Xilinx Core Generator.
After looking at the Core Generator FFT module datasheet, I see that the FFT core is expecting the data in complex format.
The data I want to transform is from an ADC and will be held in an array, the sampling will be constant rate.
Do I have to calculate the phase from the sample number and then apply the data to the FFT core?
I need to read The Scientist & Engineer's Guide to Digital Signal Processing.
I suppose what I am asking is "can I make a core for real DFT"?
