spectrum that is not present at the input.
TOTAL HARMONIC DISTORTION (THD) is the ratio, expressed in dBc, of the rms total of the first five harmonic
levels at the output to the level of the fundamental at the output. THD is calculated as
where
• f
1
is the RMS power of the fundamental (output) frequency
• f
2
through f
6
are the RMS power in the first 5 harmonic frequencies (1)
TOTAL UNADJUSTED ERROR is the worst deviation found from the ideal transfer function. As such, it is a
comprehensive specification which includes full scale error, linearity error, and offset error.
