harmonic wave; harmonic
Technical term used in physics and engineering for a wave whose frequency is an integer multiple of a fundamental frequency.
This device separates the fundamental wave and the harmonic wave.
Analyzing the harmonic components reveals the cause of the distortion.
modulated wave
harmonic; higher harmonic
total harmonic distortion; THD
Compound of 調 (tune, adjust) and 波 (wave), likely a calque from English 'harmonic wave'.
