TOTAL HARMONIC DISTORTION (THD) is the ratio, expressed in dBc, of the rms total of the first six harmonic
levels at the output to the level of the fundamental at the output. THD is calculated as:
(2)
where f
1
is the RMS power of the fundamental (output) frequency and f
2
through f
6
are the RMS power in the first
6 harmonic frequencies.
SECOND HARMONIC DISTORTION (2ND HARM) is the difference expressed in dB, between the RMS power in
the input frequency at the output and the power in its 2nd harmonic level at the output.
THIRD HARMONIC DISTORTION (3RD HARM) is the difference, expressed in dB, between the RMS power in
the input frequency at the output and the power in its 3rd harmonic level at the output.
