Devices for controlling harmonic distortion
Webdistortion within the audio bandwidth (20Hz to 20kHz). In audio applications, total harmonic distortion plus noise (THD+N) is usually measured with specialized equipment, such as the Audio Precision System One. The output signal amplitude is measured at a given frequency (e.g., 1kHz); then the fundamental signal is removed WebIn this chapter, sources of harmonic distortion are identified with the focus being on modern equipment as well as effects including impact on equipment behaviour. Whilst …
