harmonic distortion
harmonic distortion n (Electronics) electronics distortion caused by nonlinear characteristics of electronic apparatus, esp of audio amplifiers, that generate unwanted harmonics of the input frequencies Translationsharmonic distortion
harmonic distortion[här′män·ik di′stȯr·shən] (electronics) Nonlinear distortion in which undesired harmonics of a sinusoidal input signal are generated because of circuit nonlinearity. harmonic distortionIn communications, unwanted frequencies that are generated as multiples of the original frequency due to irregularities in the transmission line. In audio amplifiers, harmonic distortion comes from non-uniform operation (non-linearity) in the amplifier circuits. See harmonic.Harmonia axyridis
