Satellites in geostationary orbits are far enough away from Earth that communication latency becomes significant — about a quarter of a second for a trip from one ground-based transmitter to the satellite and back to another ground-based transmitter ; close to half a second for a round-trip communication from one Earth station to another and then back to the first.

A radio-frequency alternating current is passed through a coil of wire that acts as the transmitter, and a second coil or conducting object, magnetically coupled to the first coil, acts as the receiver.

A radio transmitter is an electronic circuit which transforms electric power from a battery or electrical mains into a radio frequency alternating current, which reverses direction millions to billions of times per second.

ENIAC had twenty ten-digit signed accumulators which used ten's complement representation and could perform 5, 000 simple addition or subtraction operations between any of them and a source ( e. g., another accumulator, or a constant transmitter ) every second.

However, once IMER acquired XERF, it was left with the old, broken transmitter, for which there were no parts, and a second, 50 kW transmitter, which was also having problems, and XERF operated with only 15, 000 watts.

As a result, at each end both a transmitter ( to send a signal over a first wavelength ) and a receiver ( to receive a signal over a second wavelength ) will be required.

The second generation mobile phones ( circa 1978 through 1990 ) could be easily monitored by anyone with a ' scanning all-band receiver ' because the system used an analog transmission system-like an ordinary radio transmitter.

If one transmitter sets SDA to 1 ( not driving a signal ) and a second transmitter sets it to 0 ( pull to ground ), the result is that the line is low.

The MSF transmitter is switched off for brief intervals ( on-off keying ) near the beginning of each second to encode the current time and date.

The small low-power transmitter only allowed a data transmission rate of 2, 048 bits per second, though the system performed data compression to squeeze more information through the narrow bandwidth.

By 1982, the company was in good health, and it easily beat off weak competition to secure a second contract ( although it lost the Blue Bell Hill transmitter near Maidstone to TVS as part of a re-organisation of the new South and South East dual-region ).

A crystal radio tuned to a strong local transmitter can be used just as a power source for a second amplified receiver for distant stations that cannot be heard with a plain crystal radio.

The tower is Auckland's primary FM radio transmitter, and its second major terrestrial television transmitter ( after Waiatarua in the Waitakere Ranges to the west ).

Also, in the part of the near-field closest to the antenna ( called the " reactive near-field ", see below ), absorption of electromagnetic power in the region by a second device has effects that feed-back to the transmitter, increasing the load on the transmitter that feeds the antenna by decreasing the antenna impedance that the transmitter " sees ".

For the audio part, MTS uses subcarriers on the video that can also carry three audio channels, including one for stereo ( same left-minus-right method as for FM ), another for second audio programs ( such as descriptive video service for the vision-impaired, and bilingual programs ), and yet a third hidden one for the studio to communicate with reporters or technicians in the field ( or for a technician or broadcast engineer at a remote transmitter site to talk back to the studio ), or any other use a TV station might see fit.

This bill would require installation of a second cockpit voice recorder, digital flight data recorder system and emergency locator transmitter that utilizes combination deployable recorder technology in each commercial passenger aircraft that is currently required to carry each of those recorders.

The Croydon Transmitter, a TV transmitter tower stands on the hill at Upper Norwood and a second larger TV transmitter, the Crystal Palace Transmitter, stands in Crystal Palace Park, making the district a landmark location, visible from any part of the London area.

A second twitched his shirtsleeve, and he felt a brief burn on his upper arm.

Greg himself took two flights, with Todman leading the second, to patrol and look for targets of opportunities around Ormoc on the east coast of Leyte.

A phony blonde hanging onto a bygone youth and beauty, but irreparably stringy in the neck, she was already working on her second gin and tonic, though it was not yet ten A.M.

And one finds it again in Thomas Nelson Page ) to the effect that the Mayflower on its second voyage brought a cargo of Negro slaves.

The first half of The Charles Men, ending on the climax of the battle of Poltava in 1709, is more dramatically coherent than the second.

The second specific comment was the report of Eisenhower's Commission on National Goals, titled Goals For Americans.

The second involves something deeper, but its characteristic form focuses on a shift in policy for the community, not in the truth on which the community rests.

Its second press release was on January 15, 1958, and it recommended that the secret papers be destroyed.

Peter Marshall noted that Bang-Jensen had later referred to his two interviews with the Gross group as `` unfortunate experiences '', and after his second meeting on the sixteenth the Dane refused to attend further hearings without legal counsel.

Sometimes, Mrs. Coolidge would close herself in the Green Suite on the second floor, and play the piano she had brought to the White House.

One shawl was so tremendous that she could not wear it, so she draped it over the banister on the second floor, and it hung over the stairway.

There is a second feature of the influences of literature, good literature, on emotional life which may have some special value for our time.

We did not dare speak to so exalted a being, but Norton aimed his camera and shot him, so to speak, on the rise, the split second between the halt and the turn.

Upon second thought we were forced to realize that we have very few reliable historical benchmarks against which we might compare the present situation, and that conclusions that present-day students are `` more '' or `` less '' religious could not be defended on the basis of our data.

The framing scenes, on the other hand, both take place in the late Spring of 1940, just at the moment of the defeat of France in the second great world conflict.

The 15th Street deposit is not to be confused with the nearby famous Mayflower Hotel cypress swamp on 17th Street reported in The Washington Post, August 2, 1955, which was probably formed during the second interglacial period and is therefore much younger.

Even apart from the fact that now at the age of 31 my personal life is being totally disrupted for the second time for no very compelling reason -- I cannot help looking around at the black leather jacket brigades standing idly on the street corners and in the taverns of every American city and asking myself if our society has gone mad.

Mickie sat over his second whisky-on-the-rocks in a little bar next to the funeral parlor on Pennsylvania Avenue.

the next a headless horror on a horse that bolted through the redcoat ranks, and during the next second or two, we all of us fired into the suddenly disorganized column of soldiers.

The ledger was full of most precise information: date of laying, length of incubation period, number of chick reaching the first week, second week, fifth week, weight of hen, size of rooster's wattles and so on, all scrawled out in a hand that looked more Chinese than English, the most jagged and sprawling Alex had ever seen.

A second and also good practice is to shear off the tops, leaving an inch high stub with just a leaf or two on each branch.

I like to shear half my plants at a time, leaving one half of them to blossom while the second half is getting started on its new round of blooming.

At the Westminster KC Dog Show in Madison Square Garden, New York on the second day, the Finals of the Junior Class brought out the most competitive competition in the history of this Class.
