ESA organised the global network of ground stations to collect the measurements of GIOVE-A / B with the use of the GETR receivers for further systematic study.

( There are two receivers in case one should be dropped and damaged.

There are many types of electronic amplifiers, commonly used in radio and television transmitters and receivers, high-fidelity (" hi-fi ") stereo equipment, microcomputers and other electronic digital equipment, and guitar and other instrument amplifiers.

While an unlicensed satellite dish can often be identified easily, satellite radio receivers are much more compact and can rarely be easily identified, at least not without flagrantly violating provisions against unreasonable search and seizure in the Canadian Charter of Rights and Freedoms.

The Food and Drug Administration regulations in are used to strictly limit, for instance, television receivers to 0. 5 milliroentgens per hour ( mR / h ) ( 0. 13 µC /( kg · h ) or 36 pA / kg ) at a distance of from any external surface ; since 2007, most CRTs have emissions that fall well below this limit.

He also doubts the concept that cultural agents are passive receivers of information.

This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, including extraction of modulation from radio signals in radio receivers — these diodes are forms of rectifiers.

For example, diodes are used to regulate voltage ( Zener diodes ), to protect circuits from high voltage surges ( avalanche diodes ), to electronically tune radio and TV receivers ( varactor diodes ), to generate radio frequency oscillations ( tunnel diodes, Gunn diodes, IMPATT diodes ), and to produce light ( light emitting diodes ).

These are important in PLL ( phase-locked loop ) and FLL ( frequency-locked loop ) circuits, allowing tuning circuits, such as those in television receivers, to lock quickly.

At the time of launch, the DSN had a small number of K < sub > a </ sub > receivers installed on an experimental basis ; K < sub > a </ sub > operations and missions are increasing.

Egypt is following closely the efforts to standardize WiMax technologies as they permit simpler and faster access to Internet services, especially as WiMax receivers are integrated into PC processors.

Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receivers needed for such systems.

Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits.

LC oscillators are often used at radio frequencies, when a tunable frequency source is necessary, such as in signal generators, tunable radio transmitters and the local oscillators in radio receivers.

Product mixers can either up-convert or down-convert an input signal frequency, but they are more commonly used to down-convert to a lower frequency to allow for simpler filter designs, as done in superheterodyne receivers.

These double-balanced mixers are very widely used in microwave communication systems, satellite communication systems, and ultrahigh frequency ( UHF ) communications transmitters and receivers, and in radar systems transmitters and receivers.

There are many types of electronic amplifiers, commonly used in radio and television transmitters and receivers, high-fidelity (" hi-fi ") stereo equipment, microcomputers and other electronic digital equipment, and guitar and other instrument amplifiers.

All defensive players are eligible receivers and offensive players who are not wearing an ineligible number are eligible receivers if they meet one of the following three criteria:

Of the players on the line of scrimmage, only the two players on the ends of the line of scrimmage are eligible receivers.

The four remaining players in the backfield ( five in Canadian football ), including the quarterback, are also eligible receivers — except in the National Football League, where a quarterback who takes the snap from " under center " is never eligible.

Factories in the US supplied Americans with Norden bomb sights and M1 Garand rifle receivers, while factories in Germany provided their armed forces with weapons.

* Upper Receiver: The majority of the SPR upper receivers were initially supplied by Colt, with others being produced by Colt Canada ( then Diemaco ).

* Upper and lower receivers: The rifles were produced by the Army Marksmanship Unit ( AMU ) at Fort Benning, Georgia using either new semi-automatic ArmaLite lower receivers or existing Army M16A2 or A4 lower receivers previously supplied by either Colt or Fabrique Nationale de Herstal.

It uses electronic radio transmitters and receivers operating at 5. 8 GHz ( MD5885 ) supplied by the Norwegian companies Q-Free and Fenrits.

And no messages can be transmitted on these circuits until senders and receivers authenticate in advance, by special codes, that the messages actually come from their purported sources.

Several years ago headlines were made by a small radio transmitter capsule which could be swallowed by the patient and which would then radio internal pressure data to external receivers.

For example, the introduction of FM stereo transmission allowed backward compatibility since new FM radio receivers could receive monaural signals generated by old transmitters.

This technique uses infrared transmitters and receivers to measure the amount of light reflectance by blood near different areas of the brain.

( t ) he use of two channels, one transmitting the predominating color ( signal T ), and the other the mean brilliance ( signal t ) output from a single television transmitter to be received not only by color television receivers provided with the necessary more expensive equipment, but also by the ordinary type of television receiver which is more numerous and less expensive and which reproduces the pictures in black and white only.

Without data decoding, the carrier can be detected by much simpler ground antennas and receivers.

During July, 1887, he conducted successful tests on the Atlantic telegraph cable between Weston-super-Mare and Waterville, Nova Scotia operated by the Commercial Company, with a double Baudot installed in duplex, the Baudot transmitters and receivers substituted for the recorder.

In the CFL ineligible receivers must wear numbers 50 to 69 ; all other numbers ( including 0 and 00 ) may be worn by eligible receivers.

In the CFL all players become eligible receivers if a pass is touched by a member of the defensive team.

However, as of February 2009, at least four players must wear numbers between 50 and 79 on first, second, or third down, which by rule would make them ineligible receivers.

Fleming's diode was used in radio receivers and radars for many decades afterwards, until it was superseded by solid state electronic technology more than 50 years later.

It scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are.

Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to a large number of receivers.

Most modern navigation relies primarily on positions determined electronically by receivers collecting information from satellites.

Scientific instruments were developed to magnify human powers of observation, such as weighing scales, clocks, telescopes, microscopes, thermometers, cameras, and tape recorders, and also translate into perceptible form events that are unobservable by human senses, such as indicator dyes, voltmeters, spectrometers, infrared cameras, oscilloscopes, interferometers, geiger counters, x-ray machines, and radio receivers.

Over 160 radio stations existed by the mid-1980s, and transistorized radio receivers were common.

However, in college and high school ball, quarterbacks are eligible receivers ( by a special exemption in the high school rule books ) regardless of whether they are under center or in a shotgun formation.

Tesla also used sensitive electromagnetic receivers, that were unlike the less responsive coherers later used by Marconi and other early experimenters.

Coached by Don Coryell ( with an offense nicknamed " Air Coryell "), featuring Fouts throwing to tight end Kellen Winslow and wide receivers John Jefferson and Charlie Joiner, they clinched their first playoff berth in 14 years with a 35 – 0 victory against the New Orleans Saints.

In the week prior to the game, Chiefs cornerback Fred " The Hammer " Williamson garnered considerable publicity by boasting he would use his " hammer "-- forearm blows to the head — to destroy the Packers ' receivers, stating " Two hammers to ( Boyd ) Dowler, one to ( Carroll ) Dale should be enough.
