  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. dBFS - Wikipedia

    en.wikipedia.org/wiki/DBFS

    Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined maximum peak level. The unit is similar to the units dBov and decibels relative to overload (dBO). [1] The level of 0 dBFS is assigned to the maximum possible digital level. [2]

  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. (For low distortion levels this will be almost equal to fundamental). That value is adjusted to read 100% or, equivalently, to 0 dB.

  6. Audio system measurements - Wikipedia

    en.wikipedia.org/wiki/Audio_system_measurements

    Most audio components are designed to be linear across their entire operating range. Well-designed solid-state amplifiers and CD players may have a frequency response that varies by only 0.2 dB between 20 Hz to 20 kHz. [5] Loudspeakers tend to have considerably less flat frequency responses than this. Total harmonic distortion (THD)

  8. A-weighting - Wikipedia

    en.wikipedia.org/wiki/A-weighting

    A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.
