Solution
Correct Answer:
Noise
Noise refers to any unwanted electrical signal that interferes with the transmission or reception of the desired information. It is random in nature and originates from various sources, such as thermal agitation (thermal noise), atmospheric disturbances, or industrial equipment. Noise degrades the Signal-to-Noise Ratio (SNR) and can cause errors in the detected information.
This easy difficulty physics question is from the chapter communication systems, covering the topic of noise. It appeared in the 2025 exam.
