The frequency domain representation of a periodic signal is a line spectrum . It can only have non-zero values at DC, the fundamental frequency, and harmonics of the fundamental. Because periodic signals have no beginning or end, non-zero periodic signals have infinite energy but generally have finite power.
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.
Read moreWhat is the spectrum of a digital signal?
A signal can also be considered as a composition of various sinusoidal signals having varied frequency, amplitude and phase. And frequency spectrum of a digital signal is its measure of energy density and presentation in the frequency domain depending on the Fourier Transform .
Read moreWhat is phase spectrum of a signal?
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 spectrum and how it is work?
Spectrum refers to the invisible radio frequencies that wireless signals travel over . Those signals are what enable us to make calls from our mobile devices, tag our friends on Instagram, call an Uber, pull up directions to a destination, and do everything on our mobile devices.5 Haz 2018

Spectrum is the range of colors of wavelength energy sent out from a light source when viewed through a prism. An example of a spectrum is a rainbow . The range of electromagnetic radiation (electromagnetic waves) in our known universe, which includes visible light.
