Question

There are many types of noise. of the noise types below, which is NOT correctly defined? Select one: Johnson noise- random fluctuations of electrons in electronic devices shot noise- noise that arises from random variation in the number of photons reaching the detector or small number of electrons and holes generated in a semiconductor drift noise- low frequency noise caused by flickering or drifting of light intensity Gaussian noise -noise amplitude is dependent on frequency line noise - noise that occurs at discrete frequencies

Explanation / Answer

Ans e. Line loise - noise that occurs at discrete frequencies

line noise refers to the disruption of that occurs in data transmissions due to interference of stray electromagnetic signals. It consists of small variations to the voltage level carried through standard AC current.
