Digital signals also store more information in an electromagnetic wave, but they only use particular, discrete values.

数字信号也在电磁波中存储更多信息，但它们仅使用特定的离散值。

Digital only takes on certain discrete values and it has a finite number of those values.

数字仅采用某些离散值，并且这些值的数量有限。

So an analog wave or signal will smoothly sweep across the infinitely many possible values it has while a digital wave or signal will only be at one of a number of discrete values.

因此，模拟波或信号将平滑地扫过其具有的无限多个可能值，而数字波或信号将仅处于多个离散值之一。
