载波频率基本定义在信号传输的进程中，并不是将信号直接进行传输，而是将信号与一个固定频率的波进行相互作用。这个进程称为加载，这样的一个固定频率的波称为载波频率。

(The carrier frequency is basically defined in the process of signal transmission. Instead of transmitting the signal directly, the signal interacts with a wave of a fixed frequency. This process is called loading, and such a fixed frequency wave is called the carrier frequency.)
