Total Harmonic distortion (THD-F): It is measured as the ratio to the RMS value of the fundamental component of the
source waveform. Reported as a percentage and calculated using the following equation:

Phase calculation: The frequency domain can be expressed in polar form. In this notation, real (Re[ ])& imaginary (Im[ ])
component in frequency domain are replaced with two other arrays, called the Magnitude is Mag[i], and the Phase is written
as: σ. The magnitude and phase are a pair-for-pair replacement for the real and imaginary parts.
Where:
i is the Index of harmonics.
Rel[i] is the Real component of the harmonics (Cos frequency).
Img[i] is the Imaginary component of the harmonics (Sin frequency).
If, Rel [k] < 0 & Im[k] < 0 Phase[k] = Phase[k] - π
