Which is twice the fundamental frequency.

这等于基频两倍。

But your vocal chords are also producing a bunch of little vibrations on top of that big vibration of the fundamental frequency.

但是你声也在基本频率大震动之了一系列小振动。

Guitars are also tuned so that the fundamental frequencies of their strings, correspond to set notes.

吉他也被调整以响应 基本频率，音调。

Because, remember: the frequency of each harmonic is equal to the number of the harmonic, times the fundamental frequency.

每个频率等于 数乘以基频。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic’s frequency.

数量等于您乘以基频数量， 得到频率。

You're creating a base tone or fundamental frequency at about 262 hertz because your vocal chords are vibrating back and forth 262 times a second.

你正在创造一个大约 262 赫兹基音或基频，因为你声每秒来回振动 262 次。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic's frequency.

数量等于你乘以数量 通过基频，求出频率。

The first partial vibrates at twice the frequency of the fundamental. The next partial is three times the fundamental’s frequency, and so on.

第一部分振动频率是基本频率两倍。下一个部分是基频三倍，依此类推。

The frequency of a standing wave with two fixed ends will just be equal to the number of the harmonic, times the fundamental frequency.

两端固定驻频率为 数乘以基频。

But for a pipe that’s closed on one end, you can’t double the fundamental frequency, or quadruple it -- or multiply it by any even number.

但是对于一端封闭管道，您不能将基频加倍或四倍——或乘以任何偶数。

So if the signal is made up of eight samples, then the transform has eight frequency bins going from zero up to seven times the fundamental frequency.

因此，如果信号由八个样本组成，则变换具有从零到基频七倍八个频率仓。
