A communication system is a system that allows the transfer of information from one point to another. Communication systems have revolutionized the way we communicate, enabling us to share information over long distances with ease. In this article, we will discuss the basics of communication systems, their components, and their applications.
The transmitter converts the message signal into a form that can be transmitted over the communication channel. The channel is the medium through which the message signal is transmitted, and the receiver converts the received signal back into the original message.
Communication systems can be classified into two types: analog and digital. In analog communication systems, the message signal is analog, which means it varies continuously over time. In digital communication systems, the message signal is digital, which means it consists of a sequence of discrete values.
