Elements of a Communication System - Physics Class 12 - NEET
Communication
Faithful transmission of information from one place to another place is called communication.
Optical fibers are used in optical communication.
Fig: Communication system
Communication System:
A communication system contains three main parts:-
(i) Transmitter: It process and encode the information and make it suitable for transmission.
The message signal for communication can be analog signals or digital signals.
An analog signal can be converted suitably into a digital signal and vice-versa.
[An analog signal is that in which current or voltage value varies continuously with time.
A digital signal is a discontinuous function of time. Such a signal is usually in the form of pulses.]
(ii) Communication Channel: The medium through which information propagate from transmitter to receiver is called communication channel.
(iii) Receiver: It receives and decode the signal.
Analog Signal:
A signal in which current or voltage changes its magnitude continuously with time, is called an analog signal.
Digital Signal:
A signal in which current or voltage have only two values, is called a digital signal.
Note An analog signal can be converted suitable Into a digital signal and vice-versa.

FAQs on Elements of a Communication System - Physics Class 12 - NEET
| 1. What are the main elements of a communication system? |  |
Ans. The main elements of a communication system include a sender, a message, a channel, a receiver, and feedback. The sender is the person or entity who initiates the communication. The message is the information or content being communicated. The channel is the medium through which the message is transmitted, such as a phone line or the internet. The receiver is the person or entity receiving the message. Feedback is the response or reaction from the receiver, which completes the communication loop.
| 2. How does the sender play a crucial role in a communication system? | |
Ans. The sender plays a crucial role in a communication system as they are responsible for initiating the communication process. They encode their thoughts or information into a message that can be understood by the receiver. The sender needs to consider factors such as clarity, relevance, and appropriateness when formulating the message. It is important for the sender to ensure that the message is effectively transmitted and received by the intended receiver.
| 3. What is the significance of feedback in a communication system? | |
Ans. Feedback is of great significance in a communication system as it completes the communication loop. It allows the sender to understand whether the message has been successfully transmitted and understood by the receiver. Feedback can be verbal or non-verbal, and it helps in verifying the accuracy and effectiveness of the communication. It also allows for clarification or further explanation if the message was not fully understood by the receiver.
| 4. How does the channel affect the communication process? | |
Ans. The channel plays a crucial role in the communication process as it determines how the message is transmitted from the sender to the receiver. Different channels have different characteristics and limitations. For example, face-to-face communication allows for immediate feedback and non-verbal cues, while written communication may lack these aspects. The choice of channel can impact the clarity, speed, and accuracy of the communication. It is important to choose an appropriate channel based on the nature of the message and the intended receiver.
| 5. What role does the receiver play in a communication system? | |
Ans. The receiver plays a vital role in a communication system as they are responsible for decoding and interpreting the message sent by the sender. The receiver's understanding of the message depends on factors such as their knowledge, language skills, and ability to pay attention. It is important for the receiver to actively listen and provide feedback to ensure effective communication. Their interpretation of the message may also be influenced by their own biases and experiences.
