Total Harmonic Distortion (THD)

THD is typically the ratio of the rms sum of the input

signal’s first four harmonics to the fundamental itself.

This is expressed as:

( ) THD = 20×log V22+ V32+ V42+ V52 / V1

where V1 is the fundamental amplitude, and V2 through

V5 are the amplitudes of the 2nd- through 5th-order

harmonics.

Spurious-Free Dynamic Range (SFDR)

SFDR is the ratio expressed in decibels of the rms

amplitude of the fundamental (maximum signal compo-

nent) to the rms value of the next largest spurious com-

ponent, excluding DC offset.

Intermodulation Distortion (IMD)

The two-tone IMD is the ratio expressed in decibels of

either input tone to the worst 3rd-order (or higher) inter-

modulation products. The individual input tone levels

are at -6.5dB full scale, and their envelope is at -0.5dB

full scale.
