Which of the following defines frequency domain?
A)Square waves are made up of the fundamental and its odd -numbered harmonics
B)Amplitude is viewed as a function of frequency rather than of time
C)Amplitude of each harmonic decreases as the frequency increases
D)Any or all of the sine or cosine terms may be zero, and there are no restrictions on their amplitudes

Question

Quizplus · Accepted Answer

Frequency domain is a representation of a signal as a function of frequency rather than of time. It describes the amplitude and phase of each frequency component that makes up the signal. Therefore, option B is the correct definition of frequency domain. Option A describes the composition of a square wave, option C describes the behavior of harmonics, and option D describes the general form of a Fourier series.
