Tag: What is frequency

A radio communications signal must occupy a range of frequencies carrying most of its energy, called its bandwidth. A frequency band may represent one communication channel or be subdivided into many . Allocation of radio frequency ranges to different uses is a major function of radio spectrum allocation.

Frequency describes the number of waves that pass a fixed place in a given amount of time . So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

Communications. Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones , to name a few. Radio frequencies are also applied in carrier current systems including telephony and control circuits.
