TMS320F28335: How to perform harmonic content analysis on an array of sinusoidal waveforms handled by ADC DMA

Hi team,

Here's an issue from the customer may need your help:

How to perform harmonic content analysis on an array of sinusoidal waveforms handled by the ADC DMA? TI's FFT library has only the amplitude, phase, frequency output of harmonics, how to get the harmonic THD content of the waveform, i.e. how does the DSP determine the sinusoidal of the waveform?

Could you help check this case? Thanks.

Best Regards,

Cherry
