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 ...
The signal-to-noise and distortion ratio (SINAD) is a measure of the quality of a signal from a communications device, often defined as = + + +, where is the average power of the signal, noise and distortion components.
The usefulness of blind listening tests and common objective performance measurements, e.g., THD, are questioned. [18] 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.
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.

If a waveform has been digitized, the correct RMS value may be calculated directly. Most digital and PC-based oscilloscopes include a function to give the RMS value of a waveform. The precision and the bandwidth of the conversion is entirely dependent on the analog to digital conversion.
In a series of videos, the man responsible for the deadly New Year’s attack in New Orleans discussed planning to kill his family and having dreams that helped inspire him to join ISIS, according ...
Vinyl microgroove phonograph records typically yield 55-65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB. [25] German magnetic tape in 1941 was reported to have had a dynamic range of 60 dB, [26] though modern-day restoration experts of such tapes note 45-50 dB as the observed dynamic range. [27]
