The signal spectrum describes a signal’s magnitude and phase characteristics as a function of frequency . The system spectrum describes how the system changes signal magnitude and phase as a function of frequency.
Read moreWhat is the phase spectrum?
The phase spectrum specifies the phase of signal components as a function of . component frequency . This phase is measured with respect to a cosine reference.
Read moreWhat is frequency spectrum analysis?
In theory, Fourier theorem states that a signal is composed of a number of sinusoidal signals. Analyzing the amplitude, frequency, and phase of these sinusoidal signals is referred to as the frequency spectrum analysis of the signal.
Read moreWhy do we need a frequency spectrum to analyze signals?
By analyzing the spectra of electrical signals, dominant frequency, power, distortion, harmonics, bandwidth, and other spectral components of a signal can be observed that are not easily detectable in time domain waveforms .
Read moreWhat is the spectrum of a function?
What is a Spectrum? • A signal is a function of time which can be represented by a series of sinusoidal functions or sinusoidal components . • These sinusoidal components have different frequencies, different amplitudes, and different phases.
