We knew the enemy was subdued, because a flare was fired as the signal.

For this reason, the more uncertain skywave service was denominated `` secondary '' in our rules, as compared to the steadier, more reliable groundwave `` primary service '', and, for both skywave service and skywave interference, signal strength is expressed in terms of percentage of time a particular signal-intensity level is exceeded -- 50 percent of the time for skywave service, 10 percent of the time for skywave interference.

The spectrometer was adjusted to minimize the amount of dispersion mode mixed in with the absorption signal.

This measurement was obtained by W. Blumberg of the University of California, Berkeley, by observing the breadth of the free induction decay signal.

I turned left too soon and got a signal showing that I was still behind him but he was to the right.

After a while the signal became a buzz and I knew he was behind me.

His signal was coming loud and clear and then all of a sudden it turned to a buzz.

There was no word spoken, no apparent signal given.

As if this was a signal, Poet abruptly began to thrash the water and the quick movement slowly made them sink through the water.

And it was clear that Adrien was not mistaken, for both Small and Cromwell took no step toward aiding in the sending up of the new topgallant mast till Philip Spencer had given the signal to obey.

His election was the signal for seven southern slave states to declare their secession from the Union and form the Confederacy.

When the Israelites, led by Joshua toward the Promised Land, arrived at the banks of the River Jordan, the Ark was carried in the lead preceding the people and was the signal for their advance ( Joshua 3: 3, 6 ).

Historically, before the advent of widespread digital technology, ASP was the only method by which to manipulate a signal.

When analog television was developed, no affordable technology for storing any video signals existed ; the luminance signal has to be generated and transmitted at the same time at which it is displayed on the CRT.

It was observed that E. coli deprived of glucose produce cAMP that serves as an internal signal to activate expression of genes for importing and metabolizing other sugars.

The Amir had scarcely suppressed it by winning a desperate battle when Abdur Rahman's reappearance in the north was a signal for a mutiny of the troops stationed in those parts and a gathering of armed bands to his standard.

The Amir Sher Ali marched up against them from Kandahar ; but in the battle that ensued at Sheikhabad on May 10, he was deserted by a large body of his troops, and after his signal defeat Abdur Rahman released his father, Afzul Khan, from prison in Ghazni, and installed him upon the throne as Amir of Afghanistan.

The three men stepped out to the side to wait for Captain Clemens' signal.

He chuckled and gave the signal for the dance to start.

Even he does not know the one signal for a nuclear strike -- the `` go code ''.

but let the twenty-five thousand and first butchery be the signal for the arrest of the 50 state highway commissioners.

Indeed, the failure of home-building as a whole to respond this year to somewhat greater availability of mortgage financing, and the increasing reports of pockets of unsold homes and rising vacancy rates in apartment buildings, may also signal in part that the lush days of big backlog demand for housing are reaching an end.

`` The pattern '', says Dr. Morton Schillinger, psychologist at New York's Lincoln Institute for Psychotherapy, `` is for the husband to hover about anxiously and eagerly, virtually trembling in his hope that she will flash him the signal that tonight is the night ''.

In practice the law had little effect, but it did signal political support for abolishing slavery in the Confederacy

Due to the averaging it is far more stable than any clock would be alone ( see signal averaging for a discussion ).

When looking for a long-term partner more conventional altruism may be preferred which may indicate that he is also willing to share resources with her and her children while when looking for a short-term partner heroic risk-taking, which may be costly signal showing good genes, may be more preferable.

An analog or analogue signal is any continuous signal for which the time varying feature ( variable ) of the signal is a representation of some other time varying quantity, i. e., analogous to another time varying signal.

The main advantage is the fine definition of the analog signal which has the potential for an infinite amount of signal resolution.

By this scheme, pulling one signal to clear locks all the other switch and signal levers in safe positions until the first signal is again restored to normal.

Along these the bifurcated impulse travels simultaneously to signal more than one other cell.

The term analog signal usually refers to electrical signals ; however, mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

Each sideband is equal in bandwidth to that of the modulating signal, and is a mirror image of the other.

It is therefore essential to keep the raster scanning in the camera ( or other device for producing the signal ) in exact synchronization with the scanning in the television.

The cAMP produced by AC then serves as a regulatory signal via specific cAMP-binding proteins, either transcription factors or other enzymes ( e. g., cAMP-dependent kinases ).

Bessel functions also have useful properties for other problems, such as signal processing ( e. g., see FM synthesis, Kaiser window, or Bessel filter ).

For example, a clock signal is subject to the delays of any other electrical signal.

This is acceptable for devices such as desk calculators, digital signal processors, and other specialised devices.

A great deal is known about low-level signal processing in sensory systems, but the ways by which sensory systems interact with each other, with " executive " systems in the frontal cortex, and with the language system are very incompletely understood.

As Grey's Anatomy is on ABC, but is carried in Canada on CTV at the same time, for instance, the cable, satellite, or other broadcast distributor must send the CTV feed over the signal of the carried ABC affiliate, even where the ABC version is somehow different, particularly commercials.

Such radiation of a potentially exploitable signal, however, occurs also with other display technologies and with electronics in general.

As chemistry and other technologies advanced, it became expedient to use coloration as a signal for telling apart things that would otherwise be confusingly similar, such as wiring in electrical and electronic devices, and pharmaceutical pills.
