Communication channel - Wikipedia
A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking.
Communication Channel • The channel is central to operation of a communication system – Linear (e.g., mobile radio) or nonlinear (e.g., satellite) – Time invariant (e.g., fiber) or time varying (e.g., mobile radio) • The information-carrying capacity of a communication system is proportional to the channel bandwidth
Communication systems convey information from one point to another via physical channels that propagate electromagnetic, acoustic, particle density, or other waves.

2018年8月9日 · Types Communication Channels. The Channel provides the electrical connection between the source and destination. It is a physical path between transmitter and receiver. A transmission medium (plural transmission media) is a material (solid, liquid or gas) which can propagate energy waves. For example, the transmission medium for sound received ...
form of pathway or medium. These pathways, called communication channels, use two types of media: cable (twisted-pair wire, cable, and fiber-optic cable) and broadcast (microwave, sate. lite, radio, and infrared). Cable or wire line media use physical wires of cables to tr.
Communication Systems - Block Diagram, Types, Elements, …
The communication system is a system which describes the information exchange between two points. The process of transmission and reception of information is called communication. The major elements of communication are the Transmitter of information, the Channel or medium of communication and the Receiver of information.
After a brief survey of the history of communications, this chapter will consider the basic elements that are common to any such system: a transmitter, a receiver, and a communication channel. We will also begin discussions of sig-nals and noise that will continue throughout the book.

The main components of a communication system are the transmitter, the communication channel, and the receiver. For a signal to be transmitted, it first goes through various phases, including signal representation, shaping, encoding, and modulation, before it passes to the transmission medium.
