Total harmonic distortion can be calculated from the following formula:
_________________________________________________
T.H.D. (dB) = 20 log (
√ (log
-1
(2nd))
2
+ (log
-1
(3rd))
2
+ (log
-1
(4th))
2
+ ... + (log
-1
(nth))
2
)
where 2nd, 3rd, 4th, ... nth are the values of the corresponding harmonics in dB relative to the
fundamental.
