Hi all,
I have a time domain signal and want to do an FFT to it and compare the converted value with a frequency domain signal.
Please suggest me ways do it.
I tried the FFT megacore function but i find it complex with all those sop, eop and other signals.
Suggest me a simple way by which i can have the whole of the time domain signal converted and stored in some location and then compare it with the frequency signal.
The length of the time domain signal be 1024.
Thanks
Nadeem

My simplest way is matlab:
y = fft(x,1024); %that's all
if you want to do it on fpga then you have do Fourier transform either through
(1) fft core done by vendor or
(2) design from basics.
(3) use dspbuilder. You drag fft block, set the parameters and you are done.
(4) use matlab HDL coder(not sure about the exact name but its Mathworks tool to convert matlab code such as above to HDL. I am told this is too expensive.
