The coding used to impress information on the wave can be a function of the frequency (the number of waves or cycles per second) or amplitude of the waves or cycles.

对载波中的信息进行压缩的编码方式可以是载波或周期的频率调制或振幅调制。

The time taken to complete one cycle is called the period, and the number of cycles per second is the frequency; the maximum value in either direction is the current's amplitude.

完成一次循环的时间称为周期，每秒循环的次数称为频率，任一方向的最大值称为交流电的振幅。

The height of the wave from the lowest to the highest point is its amplitude. The number of cycles per second is the wave's frequency.

从波形的最低点至最髙点的高度是它的幅度，每秒钟周期的数量是波的频率。
