Harmonic Distortion -THD, Sources & Effects:
Harmonic distortion refers to the alteration of the original waveform of a signal, caused by the presence of harmonics (integer multiples of the fundamental frequency). It occurs when a system, such as an amplifier or speaker, introduces unwanted frequencies into the signal. These additional frequencies can degrade sound quality or cause distortion in audio, video, or electrical systems.
Key Points:
Harmonic distortion occurs when higher-frequency harmonics are added to the original signal.
In audio systems, it can lead to a "muddy" or "fuzzy" sound.
It's measured in terms of Total Harmonic Distortion (THD), often expressed as a percentage.
THD is an important specification in audio equipment, amplifiers, and electronics to determine how much distortion is introduced.
