The amplitude spectrum simply gives amplitude at each frequency . The phase spectrum simply gives the phase at each frequency (Figure 2.20).
Read moreWhat is amplitude and phase spectrum of Fourier series?
Two-Sided Spectra The exponential Fourier series representation of a periodic function x(t) has amplitude coefficients Cn which are complex and can be represented by magnitude and phase. Hence, we can plot the amplitude spectrum (|Cn| versus ω) and the phase spectrum (∠Cnversusω) .
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 are the two types of frequency spectrum?
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. … Waveguide frequency bands.

Read moreWhat is a frequency spectrum made of?
The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum.
Read moreWhat is spectrum of sine wave?
A sine wave consists of a single frequency only, and its spectrum is a single point . Theoretically, a sine wave exists over infinite time and never changes.
