The electromagnetic spectrum is the range of all possible frequencies of electromagnetic waves . The spectrum is broken into regions/ranges and classified by frequency and/or wavelength. The frequency (f ) of an electromagnetic wave is a measure of how rapidly it oscillates.
Read moreIs frequency a spectrum?
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 + …)

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 considered high band frequency?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz .
Read moreWhat frequencies are in the C-band?
According to wireless testing firm Rohde and Schwarz, the C-band is all frequencies between 4 and 8GHz . When US wireless geeks talk about C-band, though, they’re talking about 3.7 to 4.2GHz—and specifically, in this case, the range from 3.7 to 3.98GHz.
Read moreWhat band should my CB be on?
1.1 Citizens’ Band (‘CB’) radio operates in the 27 MHz band. It is a short-range radio service for both hobby and business use. It is designed to be used without the need for technical qualifications. However, its use must not cause interference to other radio users.
Read moreWhat CB channel is most active?
Channel 19 is the most commonly-used channel by truck drivers on highways, to the point that some radios even have a dedicated button to bring up channel 19 instantly. In many areas of the US, other channels have been used in the past for similar purposes including 10, 17, and 21.
