宽带和基带传输的区别

宽带系统使用调制技术来减少环境中噪声的影响。宽带传输采用相位和幅度调制相结合的多通道单向传输。

基带是使用NRZ、RZ曼彻斯特双相-M码等信号码之一在介质上传输的数字信号，称为基带传输。

以下是宽带和基带传输之间的差异。

基带传输——

1. 数字信号。
2. 频分复用是不可能的。
3. 基带是双向传输。
4. 短距离信号传输。
5. 整个带宽用于单信号传输。
6. 示例：以太网将基带用于 LAN。

宽带传输——

1. 模拟信号。
2. 数据的传输是单向的。
3. 信号传输距离长。
4. 可以进行频分复用。
5. 在不同频率上同时传输多个信号。
6. 示例：用于将有线电视传输到房屋。

S.No	Baseband Transmission	Broadband Transmission
1.	In baseband transmission, the type of signalling used is digital.	In broadband transmission, the type of signalling used is analog.
2.	Baseband Transmission is bidirectional in nature.	Broadband Transmission is unidirectional in nature.
3.	Signals can only travel over short distances.	Signals can be travelled over long distances without being attenuated.
4.	It works well with bus topology.	It is used with a bus as well as tree topology.
5.	In baseband transmission, Manchester and Differential Manchester encoding are used.	Only PSK encoding is used.
