Dear C2000 expert,

Is there any reference code or examples of calculating total harmonics distortion?

Hi,

There is no library or example for calculating THD. However, you can use the FFT library for the same.

Jack, it appears we don't have code for this, and consequently, no documentation either. You should be able to just use the conventional definition of THD to compute it.

Thanks,

Sira
