They are key components in many electronic devices, particularly radio equipment, used in circuits such as oscillators, filters, tuners and frequency mixers.

This is a radio frequency ID system.

The frequency of a radio or television station is actually the carrier wave's center frequency.

Radio frequency (RF) is a rate of oscillation in the range of around to , which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

All stations share a single radio frequency communication channel.

Allocation of radio frequency ranges to different uses is a major function of radio spectrum allocation.

Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from to , with corresponding wavelengths of ten to one meters.

Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting.

Applications Coaxial cable is used as a transmission line for radio frequency signals.

Watson was in fact listening to very low frequency radio emissions caused by nature.

The high frequency high voltage power, or radio frequency energy, is transmitted into the gas within the globe through an electrode at its center.

The radio scientists measured a frequency shift in the radio waves to and from the spacecraft, while those signals traveled close to the Sun.

In radio systems, frequency modulation with sufficient bandwidth provides an advantage in cancelling naturally occurring noise.

In radio transmission maximum usable frequency (MUF) is the highest radio frequency that can be used for transmission between two points via reflection from the ionosphere ( skywave or skip propagation) at a specified time, independent of transmitter power.

On the radio from the 1920s In the early 1920s, the first radio stations were established by radio equipment manufacturers and retailers who offered programs in order to sell more radios to consumers.

Jack Phillips and Harold Bride served as radio operators, and performed fine tuning of the Marconi equipment.

The Wasserfall steering equipment converted the electrical signal to radio signals and transmitted these to the missile.

All of these waves, from the lowest frequency radio waves to the highest frequency gamma rays, are fundamentally the same, and they are all called electromagnetic radiation.

Each station is constantly tuned in on the radio frequency communication channel to pick up available transmissions.

Frequency modulation is used in radio, telemetry, radar, seismic prospecting, and monitoring newborns for seizures via EEG.

The installation of upgraded transmission equipment allows Radio Tuvalu to be heard on all nine islands of Tuvalu.

The F10.7 index is a measure of the solar radio flux per unit frequency at a wavelength of 10.7 cm, near the peak of the observed solar radio emission.

At even lower frequency, the wave is called a microwave, and at still lower frequencies it is called a radio wave.

), although the KW digraph ( ) was proposed in the 1980s by the Heathkit Company (a vendor of assembly kits for amateur radio equipment).

Instead of a tight coupling, the coil transfers energy (via loose coupling) from one resonant circuit (the primary) to the other (the secondary) resonant at the same frequency, over a number of radio frequency cycles.

The television channel Radio Caracas Television (RCTV) has enjoyed the ability to transmit over an open television frequency for the past 53 years.

The driven frequency may be called the undamped resonance frequency or undamped natural frequency and the peak frequency may be called the damped resonance frequency or the damped natural frequency.

Some of them are Radio Cardinal, Radio Ñandutí,Radio Nanawa and Radio Libre.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures.

A specific situation that I could observe closely was local radio in Oecussi , supported by an organization of Australian journalists in terms of equipment and training.

In physics, angular frequency ω (also referred to by the terms angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate.

The three radio channels eventually became today's Rai Radio 1, Rai Radio 2, and Rai Radio 3.

In physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter ν (nu).
