Communication Systems- Notes

Elements of a Communication System

 The transistor of ideas, thoughts or information from a sender to a receiver is called Communication.

The three essential elements of a communication system are:

• Transmitter
• Channel
• Receiver

A transmitter receives message signals from the sender and sends the suitably modified signal for transmission through the channel.

A channel is a physical medium, wired or wireless, that connects the transmitter and the receiver.

A message gets distorted with noise while transmission through a channel.
