Total harmonic distortions is calculated as the ratio between the fundamental power, and the square root of, sum of squares of the harmonic powers.
When the Harmonic/Spur Power Calculation method is provided as Integrate, the neighboring bins are included for both fundamental and harmonics power calculations.
When the Harmonic/Spur Power Calculation method is provided as Don’t Integrate, the neighboring bins are not included for fundamental and harmonics, in the calculation of THD.
