What is the frequency spectrum?

The

energy generated by electromagnetic radiation is generated from the forces developed by variable fluctuations of magnetic and electrical power fields that are at right angles to each other who travel at light speed. These electromagnetic disorders create waves that can be measured and that occur or pulsate at different speeds or frequencies each second. The frequency spectrum is the classification method according to their commonly understandable names, discrete and unique elements of all electromagnetic occurrences in terms of frequency of emitted energy induced every second. Radio waves, television broadcasting, X -rays, microwaves and infrared transmissions are all electromagnetic radiation, whose basic attributes can be defined and identified by the frequency or the amount of radiation that each type produces. The frequency

is defined as the number of complete electromagnetic cycles of energy waves that occur every second. International measuring unit used to describeUE cycle is 1 Hertz (Hz). Since each part of the electromagnetic spectrum has a frequency signature, it can be identified using the frequency spectrum analyzer, which is able to accurately measure wave cycles per second of a particular electromagnetic phenomenon under observation.

Each of the different forms of electromagnetic energy occupies the designated location on the frequency spectrum. The electromagnetic continuum, as is expressed in terms of the frequency or intensity of radiation emitted by each different segment, ranges from 10

6 Hz to 10 25 Hz. Radio waves occupy the lower end of the frequency spectrum, while radioactive gamma rays occupy the top end. The frequency range included in the electromagnetic spectrum is huge. The frequency of generated radio transmissions and frequencies produced by visible light varies according to the order of Million's size.

frequency spectrumFor radio transmissions, it is also classified to frequency or "belts" ranges, both as a means for minimizing interference and for sharing a bandwidth among multiple users. The International Agreement on the Union Telecommunications allocates certain ranges of radio transmission frequency to minimize interference in the shortwave radio spectrum. High -frequency tapes are assigned between international shortwave broadcasters, amateur radio operators and maritime radio communications.

To ensure reliable radio broadcasts without interference, domestic government agencies often regulate certain aspects of the frequency spectrum. In the United States of the Federal Communication Commission (FCC), it allocates frequency bands between businesses, the general public and amateur radio operators to limit the possible intervention between the bands. Each band is marked with a specific frequency range, and this spectrum is reserved for each of the different groups specific to the user.
