Question

What are the three basic components of Communication?

Answer 1

Communication:

The communication system is a system that describes the information exchange between two points. The process of transmission and reception of information is called communication.

Components of Communication:

The three essential components of a communication system are:

• Transmitter:
  • The transmitter modulates the message signal.
  • Modulation is the process of converting a signal into a form suitable for transmission.
  • A transmitter is a telecommunications electrical device that generates radio waves so that data may be transferred or received through an antenna.
  • The transmitter may generate an alternating current of radio frequency, which is then applied to the antenna, which radiates it as radio waves.
• Channel:
  • A communication channel is a physical transmission channel in telecommunications and computer networking.
  • A channel is a device that delivers data from one or more senders (or transmitters) to one or more receivers.
  • Or in other words, the channel is what connects the output of the transmitter to the receiver input.
• Receiver:
  • The receiver does the demodulation. Demodulation is the process of recovering the correct message signal.
  • The received signal, which is picked up from the broadcast signal at the channel output, is processed by the receiver to reproduce the original message signal in a recognizable form for transmission.
  • A radio receiver, also known as an FM receiver, is a device that receives radio waves and converts the data carried by them into useable information.
  • The desired frequency waves are caught using an antenna.
