Frequency spectrum of a signal is the range of frequencies contained by a signal. For example, a square wave is shown in Fig. 3.5A. It can be represented by a series of sine waves, S(t) = 4A/π sin(2πft) + 4A/3π sin(2π(3f)t) + 4A/5π sin(2π(5f)t + …)

Frequency spectrum of a signal is the range of frequencies contained by a signal .
Read moreWhat is the spectrum of a signal?
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 difference between the spectrum of a signal and its bandwidth?
The spectrum of a signal is the range of frequencies contained in the signal. The bandwidth is the difference between the lowest and highest frequency in the spectrum . It is therefore the width of the spectrum and is a measure of the information carrying capacity of the signal.

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. For example, Figure 6.6 shows the magnitude and phase spectra of some hypothetical system.

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.

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.
