unipolar signalling 单极信号传输 Data transmission in which there are only two line conditions, one of which is “neutral” (0V) and the other of which is positive (or negative, depending upon the system). A mark could, for example, be represented by +10V, and a space by 0V. 仅有两种线路状态的数据传输,即“中性”状态(0V)和正极性(或负极性,由系统决定) 状态.例如: +10V可表示一个传号,0V表示一个空号 |
