Harmonic distortion
Harmonic distortion refers to the alteration of a pure audio signal, where additional frequencies, called harmonics, are introduced. These harmonics are multiples of the original frequency and can distort the sound, making it less clear or pleasant. In practical terms, if a musical note is meant to sound a certain way, harmonic distortion can make it sound "muddy" or "off." It is commonly measured in audio equipment to assess sound quality, as lower distortion levels typically indicate clearer, more accurate reproduction of sound. Understanding harmonic distortion helps in evaluating audio devices and ensuring quality sound experiences.

Harmonic distortion refers to the alteration of a signal due to the introduction of additional frequencies, known as harmonics. These harmonics are whole number multiples of the original frequency. In simpler terms, when sound or electrical signals become distorted, they can produce unwanted notes or irregularities that affect the quality. In audio systems, this means the music may sound muddy or unclear, while in electronics, it can lead to inefficiencies and overheating. Reducing harmonic distortion is important for ensuring clear sound and reliable device performance.
