By this standard, it is determined that where two stations operating on the same frequency are involved, objectionable interference from station A exists at any point within the service area of station B where station A's signal is of an intensity one-twentieth or more of the strength of station B's signal at that point.

DTMF tones are also used by some cable television networks and radio networks to signal the local cable company / network station to insert a local advertisement or station identification.

Each station transmitted a continuous wave signal that, by comparing the phase difference of the signals from the Master and one of the Slaves, resulted in a set of hyperbolic lines of position called a pattern.

Handsets that are moving will need to constantly adjust their timings to ensure their transmission is received at precisely the right time, because as they move further from the base station, their signal will take longer to arrive.

The idea of a network system which would distribute programming to many stations simultaneously, saving each station the expense of creating all of its own programs and expanding the total coverage beyond the limits of a single broadcast signal, was devised.

* A teleprinter exchange facility signal that automatically causes a calling station to retry the call-receiver number after a given interval when the call-receiver teleprinter is occupied or the circuits are busy.

* a transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame.

The jam signal is a signal that carries a 32-bit binary pattern sent by a data station to inform the other stations that they must not transmit.

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.

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.

Essentially, the stator or reference portion of the pickoff is established with respect to the true heading direction, and the platform is turned either manually or automatically until the angular electrical pickoff signal is reduced to zero.

Well established examples are the ultra-sensitive response of the motor to the CheY-P signal, and the clustering of chemoreceptors.

* 1904 – The distress signal " CQD " is established only to be replaced two years later by " SOS ".

Moog also established standards for analog synthesizer control interfacing, with a logarithmic one volt-per-octave pitch control and a separate pulse triggering signal.

In 2005, the IAA established the SETI: Post-Detection Science and Technology Taskgroup ( Chairman, Professor Paul Davies ) " to act as a Standing Committee to be available to be called on at any time to advise and consult on questions stemming from the discovery of a putative signal of extraterrestrial intelligent ( ETI ) origin.

* January 7 – The distress signal CQD is established, only to be replaced 2 years later by SOS.

In telecommunication, the reframing time ( or frame-alignment recovery time ) is the time interval between the instant at which a valid frame-alignment signal is available at the receiving data terminal equipment and the instant at which frame alignment is established.

The space flight Head Quarters established on Olga picks up an SOS signal coming from the Earth where the first colonists of Darius originated before colonizing Darius ; the signal included the description of alien ships similar to that of the Belser Army.

Montara Light was originally established in 1875 as a fog signal station after several ships ran ashore in the late 1860s.

Moog established standards recognized worldwide for control interfacing on analog synthesizers, using a logarithmic 1-volt-per-octave pitch control and a separate pulse triggering signal.

One of the principal hills in San Francisco, California is also named " Telegraph Hill ", after the semaphore telegraph which was established there in 1849 to signal the arrival of ships into San Francisco Bay.

Coupled with the direction of the beam ( adjusted for maximum return signal ), the bomber's position could be established with considerable accuracy.

When contact with a new group of 11 survivors was established via hammer signal, newspapers and media worldwide began to speak of a miracle.

At the highest point of the mountain, in the midst of the summit level is a further tower, the 7 meters high signal tower established around 1840.

After nine months the RAF took over operations and established a signal intelligence collection unit there, known as a Y Station.

The signal format is solid white when established on the proper descent profile, and solid red when below the proper descent profile.

The settlement money expended, not to ignore the terrible loss of life, in claims and lawsuits and repairing, replacing, or scrapping wrecked rolling stock eventually exceeded what an installed block signal system would have cost in 1930 when the C & LE was first established from the three original interurbans.
