宽带网的带宽及传输技术

The Broadband of Broad Bank Network and Its Transmission Technique

从模拟条件下定义的“宽带”入手,利用付里叶级数和付氏变换这一工具,说明数字通信中用到的宽带的含义指的是数据的传输速率同时利用仙农定理进一步说明信道宽带与速率的区别和联系.也论述了构成网络的几个主要部分入手,从宏观上指出了宽带网的传输途径.

The authors explain the broadband which is used in digital communications refers to the date transmission rate on the basis of the definition of 'broadband' under simulated conditions. Then they illustrate the differences and connections between channel broadband and ratio, and also discuss the tansmission channel of broad bank through the mains parts which consist of the network.
