Web15 Nov 2024 · Total harmonic distortion (THD) is a parameter measuring the harmonic distortion present in a signal. It is defined as the ratio of the sum of the powers of all harmonic components to the power of fundamental frequency.. In audio systems, lower distortion means that the components (speakers, microphones, headphones, amplifiers) … Web13 Aug 2015 · Harmonic distortion is often stated as a measurement called Total Harmonic Distortion, or THD, which is a percentage of the overall signal composed of harmonic distortion. THD is not a good indicator of how audible harmonic distortion will be unless it is of an extremely high or extremely low value. This is because there could be relatively ...
