谐波 Harmonic

(重定向自Harmonics)
绳子抖动的模式是谐波
Tabla de armónicos en la guitarra eléctrica.
Two different notations of natural harmonics on the cello. First as sounded (more common), then as fingered (easier to sightread).

谐波是一个数学或物理学概念,是指周期函数或周期性的波形中能用常数、与原函数的最小正周期相同的正弦函数和余弦函数的线性组合表达的部分。

根据傅立叶级数的原理,周期函数都可以展开为常数与一组具有共同周期的正弦函数和余弦函数之和。
其展开式中,常数表达的部分称为直流分量,最小正周期等于原函数的周期的部分称为基波一次谐波,最小正周期的若干倍等于原函数的周期的部分称为高次谐波
因此高次谐波的频率必然也等于基波的频率的若干倍,基波频率3倍的波称为三次谐波,基波频率5倍的波称为五次谐波,以此类推。不管几次谐波,他们都是正弦波。

Harmonic 谐波

Two different notations of natural harmonics on the cello. First as sounded (more common), then as fingered (easier to sightread).

The term harmonic in its strictest sense describes any member of the harmonic series. The term is employed in various disciplines, including music and acoustics, electronic power transmission, radio technology, etc. It is typically applied to repeating signals, such as sinusoidal waves. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called 1st harmonic, the following harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz.
