  2. Total harmonic distortion - Wikipedia

    en.wikipedia.org/wiki/Total_harmonic_distortion

    These can be distinguished as THD F (for "fundamental"), and THD R (for "root mean square"). [12] [13] THD R cannot exceed 100%. At low distortion levels, the difference between the two calculation methods is negligible. For instance, a signal with THD F of 10% has a very similar THD R of 9.95%. However, at higher distortion levels the ...

  3. Total harmonic distortion analyzer - Wikipedia

    en.wikipedia.org/wiki/Total_harmonic_distortion...

    A total harmonic distortion analyzer calculates the total harmonic content of a sinewave with some distortion, expressed as total harmonic distortion (THD). A typical application is to determine the THD of an amplifier by using a very-low-distortion sinewave input and examining the output.

  4. Harmonics (electrical power) - Wikipedia

    en.wikipedia.org/wiki/Harmonics_(electrical_power)

    Total harmonic distortion, or THD is a common measurement of the level of harmonic distortion present in power systems. THD can be related to either current harmonics or voltage harmonics, and it is defined as the ratio of the RMS value of all harmonics to the RMS value of the fundamental component times 100%; the DC component is neglected.

  5. Distortionmeter - Wikipedia

    en.wikipedia.org/wiki/Distortionmeter

    A distortionmeter is a level meter with two switchable parallel circuits at the input. The first circuit measures the total signal at the output of a system.

  6. Total dynamic head - Wikipedia

    en.wikipedia.org/wiki/Total_dynamic_head

    In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.

  9. Spurious-free dynamic range - Wikipedia

    en.wikipedia.org/wiki/Spurious-free_dynamic_range

    Spurious-free dynamic range (SFDR) is the strength ratio of the fundamental signal to the strongest spurious signal in the output. It is also defined as a measure used to specify analog-to-digital and digital-to-analog converters (ADCs and DACs, respectively) and radio receivers.
