Hi,

I need some help regarding IFFT and FFt

Is there any library supplied by TI that contains IFFT (Inverse Fast Fourier Transform) functionality that can be used with the TMS320F28044 (Fixed point)?

thanks a lot,

Hello Mr Gautam,

Thank you for your response. I am using the fixed-point DSPF28044, and I want to do a ifft (Inverse Fast Fourier Transform)) for a table containing the amplitude and the phase shifted of the harmonics (3, 5, 7, 9, 11, 13) to retrieve the continuous signal. So I'm looking for a code in Fixed-point(IQ) that will make this transformation, could you help me please.

Regards,

Ousama
