(Continued)
rms value of the sum of all other spectral components below
one-half the sampling frequency, not including harmonics or
d.c.
SIGNAL TO NOISE PLUS DISTORTION (S/(N+D) or SI-
NAD)
is the ratio, expressed in dB, of the rms value of the
input signal at the output to the rms value of all of the other
spectral components below half the input clock frequency,
including harmonics but excluding d.c.
SPURIOUS-FREE DYNAMIC RANGE (SFDR)
is the differ-
ence, expressed in dB, between the rms values of the input
signal at the output and the peak spurious signal, where a
spurious signal is any signal present in the output spectrum
that is not present at the input, excluding d.c.
TOTAL HARMONIC DISTORTION (THD)
is the ratio ex-
pressed in dB, of the rms total of the first nine harmonic
levels at the output to the level of the fundamental at the
output. THD is calculated as
where A
is the RMS power of the fundamental (output)
frequency and A
through A
are the RMS power of the
first 9 harmonic frequencies in the output spectrum.
– Second Harmonic Distortion (2nd Harm)
is the differ-
ence, expressed in dB, between the RMS power in the input
frequency seen 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 fre-
quency seen at the output and the power in its 3rd harmonic
level at the output.
