Thd in a sentence

In practice, the THD F is commonly used in audio distortion specifications (percentage THD); however, THD is a non-standardized specification and the results between manufacturers are not easily comparable.

For instance, a signal with THD F 266% has a THD R of 94%.

For instance, crossover distortion at a given THD is much more audible than clipping distortion at the same THD, since the harmonics produced are at higher frequencies, which are not as easily masked by the fundamental.

There are several solutions to reduce the THD I in a double-conversion UPS: Passive power-factor correction main Classic solutions such as passive filters reduce THD I to 5%–10% at full load.

The unit has been functioning with the THD 1955 radar since 1995.

Trying to bolster belief dishonestly should not be necessary if you have thd truth.

A double-conversion UPS with an insulated-gate bipolar transistor rectifier and inductor can have a THD I as small as 2%.

A number of formulas that attempt to correlate THD with actual audibility have been published, however none have gained mainstream use.

Different types of distortion (like crossover distortion ) are more audible than others (like soft clipping ) even if the THD measurements are identical.

Harmonic distortion in radio frequency applications is rarely expressed as THD.

However, analytic computation of the THD F for complicated waveforms and filters often represents a difficult task, and the resulting expressions may be quite laborious to obtain.

In radiocommunications, lower THD means pure signal emission without causing interferences to other electronic devices.

Measurements for calculating the THD are made at the output of a device under specified conditions.

Significant efficiency gains can be achieved but with the drawback of more complicated supply design and reduced THD performance.

Taking THD measurements at different output levels would expose whether the distortion is clipping (which increases with level) or crossover (which decreases with level).

THD is an average of a number of harmonics equally weighted, even though research performed decades ago identifies that lower order harmonics are harder to hear at the same level, compared with higher order ones.

The THD is usually expressed in percent or in dB relative to the fundamental as distortion attenuation.

This level of "noise" is measured as a percentage of " total harmonic distortion of the current " (THD I ).
