What is a Communication system?
Basic communication system-
Sending, receiving, and processing information between two or more devices is referred to as communication. A communication system is a group of components that work together to create a line of communication between sender and recipient. Radio broadcasting, television broadcasting, radiotelegraphy, mobile communication, etc. are some examples of communication systems. A communication system is any two or more persons exchanging sound signals with one another.
In other terms, the system is defined as communication Communication is the act of communicating or exchanging any kind of knowledge, concepts, or emotions via any medium or route. Information movement from one location to another is the simplest definition of communication.

The basic components of a communication system-
- Information Source
- Input Transducer
- Transmitter
- Channel
- Noise
- Receiver
- Output Transducer and Destination
Explanation of Block diagram communication system
1. Information Source– In which a communication system’s information source is used to transmit messages or other types of information. The source of the information is where the information comes from. The information signal is transformed into a physical amount by the information source. The message signal is created from the physical signal.
2. Input Transducer- When the information source creates the message. There is no electrical format for this message. It is transformed into an electrical signal using an input transducer.
3. Transmitter- The transmitter gathers the incoming signal and makes necessary adjustments. The transmitter will adjust the source signal’s electric counterpart once it has been converted for effective transmission.
4. Channel-The term “communication channel” simply refers to the medium that a signal passes through. A channel is a physical link between a transmitter and a receiver or the medium via which a message is transmitted from one to the other.
Explanation of Two types of Channels-One is a point, such as a wire, an optical fiber, etc., and the other is a broadcast channel, such as a satellite in geostationary orbit that covers about one-third of the earth’s surface, that enables multiple receiving stations to be reached simultaneously from a single transmitter.
5. Noise– An unwanted signal known as noise interferes with the broadcast signal by entering the communication system through the communication channel. The transmitted signal is deteriorated by the noise signal or undesired signal.
6. Receiver-The receiver’s function is to transform the distorted received signal into an electrical form that may be used to transmit messages.
7. Output Transducer-The final stage of signal conversion from an electrical message into its original signal is output transducers and destination. The output transducer transforms electrical signals into non-electrical signals, such as sound and light. The loudspeaker, which is situated between the reception portion and the destination, is the best illustration of an output transducer. The loudspeaker transforms electrical signals into audible signals that may be easily understood by people at the target location.
