digital transmission system
数字传输系统;［数位传输系统］
In data communications, a network in which analog information is digitized via a modulation technique and transmitted in a discrete form as a series of pulses. At the receiving station, the analog data is reconstituted from the digitized signals. Digital transmission systems support high data rates, error detection and minimize effects due to noise.
数据通信中的一种网络,该网络中模拟信息通过调制技术实现数字化,并作为一串脉冲 以离散形式发送。在接收站,模拟数据可由数字化信号转换复原。数字传输系统支持高数据 率,错误检测,并能把噪声造成的影响减到最小。
