Digital signal - Wikipedia
网页In digital electronics, a digital signal is a pulse amplitude modulated signal, i.e. a sequence of fixed-width electrical pulses or light pulses, each occupying one of a discrete number of levels of amplitude.

网页数字信号是指用一组特殊的状态来描述信号，典型的就是当前用最为常见的 二进制数字 来表示的信号，之所以采用二进制数字表示信号， 其根本原因是电路只能表示两种状态，即电路的通与断。 在实际的数字信号传输中，通常是将一定范围的信息变化归类为状态0或状态1， 这种状态的设置大大提高了数字信号的抗噪声能力。 不仅如此，在 保密性 、抗干扰、传输质量等方面，数字信号都比 模拟信号 要好，且更加节约信号 传输通道 资源。 [1]

Digital signal (signal processing) - Wikipedia
网页In the context of digital signal processing (DSP), a digital signal is a discrete time, quantized amplitude signal. In other words, it is a sampled signal consisting of samples that take on values from a discrete set (a countable set that can be mapped one-to-one to a subset of integers ).
