Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

PCM语音复用设备，中文称脉码调制，由A.里弗斯于1937年提出的，这一概念为数字通信奠定了基础，60年代它开始应用于市内电话网以扩充容量，使已有音频电缆的大部分芯线的传输容量扩大24～48倍。各国相继把脉码调制成功地应用于同轴电缆通信、微波接力通信 ...
