The logarithmic measure in decibels () of how the transmitted RF signal over the NLOS link is affected by such a reflection is given by:

If an object which is responsible for changing a LOS link to NLOS is not a good conductor but an intermediate material it will absorb some of the RF power incident upon it.

This unique RF box was also where the power supply connected in a unique dual power / television signal setup similar to the RCA Studio II's.

They also tend to have much lower junction capacitance than p – n diodes, which provides for high switching speeds and their use in high-speed circuitry and RF devices such as switched-mode power supply, mixers, and detectors.

* RF power amplifier, such as for transmitter final stages ( see also: Linear amplifier ).

RF is also seen in other illnesses, for example Sjögren's syndrome, Hepatitis C, chronic infections and in approximately 10 % of the healthy population, therefore the test is not very specific.

The increase in conductivity is also taken advantage of in RF engineering at VHF and higher frequencies, where conductors often cannot be scaled by 6 %, due to tuning requirements, e. g. cavity filters.

However, if f < small >< sub > LO </ sub ></ small > is set to f < small >< sub > d </ sub ></ small > + f < small >< sub > IF </ sub ></ small >, then an incoming radio signal at f < small >< sub > LO </ sub ></ small > + f < small >< sub > IF </ sub ></ small > will also produce a heterodyne at f < small >< sub > IF </ sub ></ small >; this is called the image frequency and must be rejected by the tuned circuits in the RF stage.

With the development of the pentagrid converter, these functions were combined inside a single tube which applied the RF signal to the control grid, but also implemented the local oscillator using additional grids.

The HPA's position is that “... radio frequency ( RF ) exposures from WiFi are likely to be lower than those from mobile phones .” It also saw “... no reason why schools and others should not use WiFi equipment .” In October 2007, the HPA launched a new “ systematic ” study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time ".

That said, it is also used in the Radio Frequency ( RF ) regime for cases in which the antenna is operating in the so-called optical region and is likewise very large relative to a wavelength.

For conducted emissions, typical transducers are the LISN ( Line Impedance Stabilisation Network ) also sometimes called as the AMN ( Artificial Mains Network ) and the RF current clamp.

Signal generators, also known variously as function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators or frequency generators are electronic devices that generate repeating or non-repeating electronic signals ( in either the analog or digital domains ).

Although radio frequency is a rate of oscillation, the term " radio frequency " or its acronym " RF " are also used as a synonym for radio – i. e. to describe the use of wireless communication, as opposed to communication via electric wires.

CMOS technology is also widely used for RF circuits all the way to microwave frequencies, in mixed-signal ( analog + digital ) applications.

The outside of the device is water-cooled in order to keep the RF coil from melting and also to cool the outside of the zirconium oxide and thus maintain the shape of the zirconium powder.

RF modulators may also be used to take the audio and video signal from a PAL or NTSC composite video, RGB, YUV or other composite AV source, and generate a broadcast RF signal that can be fed into a television's aerial / coaxial connector.

RF is also " noisy " because of all of the video and radio signals already being broadcast, so this conversion also typically adds noise or interference to the signal as well.

Though RF modulators inherently transmit combined A / V signals in video applications, they depend on broadcast television systems and RF connectors which are not universal worldwide ; RF signals are also generally inferior to direct signals due to protocol conversion and the RF limitations of the three major analog TV systems ( NTSC, PAL and SECAM ).

Nearly all modern TV sets, VCRs, and DVD players sold in Europe have SCART connectors, though sometimes supplemented by RCA and / or RF connectors and there are also SCART-RCA adapters.

The model can be a linear or non-linear, time-continuous or time-discrete ( sampled ), memoryless or dynamic ( resulting in burst errors ), time-invariant or time-variant ( also resulting in burst errors ), baseband, passband ( RF signal model ), real-valued or complex-valued signal model.

Despite this opinion among researchers, evidence has accumulated that supports the existence of complex biological effects of weaker non-thermal electromagnetic fields, ( including weak ELF magnetic fields, although the latter does not strictly qualify as EM radiation < ref >), and modulated RF and microwave fields.

RF signal generators are capable of producing CW ( continuous wave ) tones.

During World War II Collins expertise grew in higher power transmitters producing designs which ran well over 15 kilowatts of RF power on a continuous basis.

A change in frequency of Morse code from the desired frequency, due to poor stability in the RF Oscillator is known as chirp, and in the RST code is given an appended letter ' C '.

Another method is known as thermolysis, RF, shortwave or diathermy.

Galvanic and thermolysis are often combined in a method known as blend, developed by Arthur Hinkel in 1948, which uses both RF and direct current, combining many of the advantages of galvanic and thermolysis.

This may then be converted to RF with an external box known as an RF modulator that generates the proper carrier ( often for channel 3 or 4 in North America, channel 36 in Europe ).

However, just as the modulation and demodulation of RF loses quality, the mixing of the various signals into the original composite signal does the same, causing a checkerboard video artifact known as dot crawl.

The RAM is designed and shaped to absorb incident RF radiation ( also known as non-ionising radiation ), as effectively as possible, from as many incident directions as possible.
