D) attenuation

Question

Quizplus · Accepted Answer

Noise refers to any unwanted signal that is not derived from or harmonically related to the input signal. Hysteresis refers to a lag in response exhibited by a system. Oscillations refer to repetitive variations of a signal, typically around a central value. Attenuation refers to a decrease in signal strength or amplitude over a distance or in a medium. None of these definitions fit the description of unwanted signals that are not derived from or harmonically related to the input signal, making C the correct answer.
