Which of the Following is not a component of communication System? (A) Transmitter (B) Transmission channel (C) Noise (D) Receiver

A communication system is designed to transmit information from a sender (source) to a receiver (destination). The basic components of a communication system typically include a transmitter, a transmission channel, and a receiver.

(A) Transmitter: The transmitter is responsible for converting the input signal into a form suitable for transmission over the communication channel. This is an important part of the communication system. (B) Transmission channel: The transmission channel is the medium through which the signal is transmitted. It can be a wired connection such as a cable, or a wireless connection using radio waves or other means. This is also an important part of the communication system. (C) Noise: Noise refers to any unwanted signal that can interfere with the transmitted signal in the communication system. Noise is not an intentional component of the system, but it is a factor that can affect the quality of the signal transmission. It is not a component of the communication system, but rather something that affects the communication system. (D) Receiver: The receiver is responsible for detecting the transmitted signal and converting it back into its original form for the destimation. This is an important part of the communication system.

Comparing each of the given options, we can confirm that (C) Noise is not a component of the communication system. Noise is something that affects the performance of the communication system, but it is not an intentional part of the system. Therefore, the correct answer is (C) Noise.
