Total harmonic distortion. the total harmonic distortion ( thd or thdi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. distortion factor, a closely related term, is sometimes used as a synonym.

Figure 1. block diagram of a thd n analyzer. thd n ratio is usually expressed either in percent or db. percent is commonly used for thd n levels of 0.01% or higher. for very low distortion, db units are easier to work with. for example, the typical residual distortion of an apx555 audio analyzer’s analog i o (figure 2) is 120 db or 0.0001%. Thd n is the inverse of sinad in that it is the sum of all spectral components of the test tone (excluding the test tone itself) over a certain bandwidth. the voltage and level of the test tone and a greater or narrower bandwith (e.g., 4v, 3dbfs, 20hz—20khz) will affect the results. Not all distortion is created equal. thd n is useful for benchmarking a product, but it doesn’t tell the full story. as discussed, thd n is a combined value of all unwanted harmonics and noise. however, it says nothing about how the harmonics are related in frequency. 6.1 even order distortion.

Total harmonic distortion is the sum of all the harmonic distortion products in a measurement, as opposed to selective harmonic distortion, which measures discrete harmonic products separately. thd n adds noise to this figure. thd n is the most common distortion measurement for audio signals. in the apx500 meter (single value) thd n and stepped.
