A distress signal from the sleeper ship eventually reaches " Relay ", a major node in the galactic communications network.

When gastric hydrochloric acid reaches the nerves in the gastrointestinal mucosa, they signal pain to the central nervous system.

When a pilot moves the control column ( or sidestick ), a signal is sent to a computer ( analogous to moving a game controller ) the signal is sent through multiple wires ( channels ) to ensure that the signal reaches the computer.

If termination is missing, or if there is a break in the cable, the AC signal on the bus is reflected, rather than dissipated when it reaches the end.

In some cases, a large number of interactions can in fact work against the emergence of interesting behaviour, by creating a lot of " noise " to drown out any emerging " signal "; the emergent behaviour may need to be temporarily isolated from other interactions before it reaches enough critical mass to be self-supporting.

* is the last signal regeneration point, on the loop side, coming from the central office, before the regenerated signal reaches a multiplexer or data terminal equipment ( DTE ).

the output signal reaches one of the limits, the PWM signal changes state.

One of the causes of intersymbol interference is what is known as multipath propagation in which a wireless signal from a transmitter reaches the receiver via many different paths.

The radiation pattern of most antennas shows a pattern of " lobes " at various angles, directions where the radiated signal strength reaches a maximum, separated by " nulls ", angles at which the radiation falls to zero.

In signal processing and telecommunication, pulse duration is the interval between the time, during the first transition, that the amplitude of the pulse reaches a specified fraction ( level ) of its final amplitude, and the time the pulse amplitude drops, on the last transition, to the same level.

For a receiver, the attack-time delay is defined as the time interval from the instant a step radio-frequency ( RF ) signal, at a level equal to the receiver's threshold of sensitivity, is applied to the receiver input, to the instant when the receiver's output amplitude reaches 90 % of its steady-state value.

KWUR was named best radio station in St. Louis of 2003 by the Riverfront Times despite the fact that its signal reaches only a few blocks beyond the boundaries of the campus.

The predictive capability of such a signal ( see also market sentiment ) is thought to be highest when investor sentiment reaches extreme values.

Because of this, a common measure to avoid denormals on processors where there would be a performance penalty is to cut the signal to zero once it reaches denormal levels or mix in an extremely quiet noise signal.

Because of the low amplitude of the signal once it reaches the patient's scalp and the relatively high amount of electrical noise caused by background EEG, scalp muscle EMG or electrical devices in the room, the signal must be averaged.

( A subtlety is that, because the Hubble parameter is decreasing with time, there can be cases where a galaxy that is receding from us just a bit faster than light does emit a signal that reaches us eventually ).

Once the soma reaches a certain potential, the axon will transmit an all-in signal pulse down its length.

By the time it reaches the minimum landing size, an individual may have molted 25 – 27 times, and thereafter each molt may signal a 40 %– 50 % increase in weight, and a 14 % increase in carapace length.

In particular, if the pulse width of the gate current is sufficiently large ( generally some tens of microseconds ), the TRIAC has completed the triggering process when the gate signal is discontinued and the latching current reaches a minimum level called holding current.

Inefficiency comes not just from the fact that the device is always conducting to some extent ( that happens even with class AB, yet its efficiency can be close to that of class B ); it is that the standing current is roughly half the maximum output current ( although this can be less with square law output stage ), together with the problem that a large part of the power supply voltage is developed across the output device at low signal levels ( as with classes AB and B, but unlike output stages such as class D ).

The average voltage at the drain is then equal to the supply voltage, and the signal voltage appearing across the tuned circuit varies from near zero to near twice the supply voltage during the rf cycle.

Where the analog signal from scanners was digitized and then compressed, resulting in the ability to transmit high rates of data across standard phone lines.

Ideally a filter would have a high attenuation to adjacent channels, but maintain a flat response across the desired signal spectrum in order to retain the quality of the received signal.

Analog TV signal feed of 5 national channels are receivable over-the-air in all living areas across the country.

Unless this is done, reflected signals will travel back and forth across the wire, positively or negatively interfering with the information-carrying signal.

They multiplexed the signal across all 8 wires thereby lowering the frequency and making it more robust.

The way this works is by having each network sending its signal to many local affiliate television stations across the country.

The network physically linked individual radio stations, nearly all of which were independent radio owned and operated station, in a vast chain, NBC's audio signal thus transmitted from station to station to listeners across the United States.

It then sends these 2 signals across the CAT5 cable as a balanced signal.

For applications in flash ADCs the distributed signal across eight ports matches the voltage and current gain after each amplifier, and resistors then behave as level-shifters.

The underlying technology of transport across DSL facilities uses high-frequency sinusoidal carrier wave modulation, which is an analog signal transmission.

It is often desirable for the group delay to be constant across all frequencies ; otherwise there is temporal smearing of the signal.

Signal compression ( in dB ) may be a linear or nonlinear function of the signal level across the frequency band of interest and may be essentially instantaneous or have fixed or variable delay times.

If the signal and the noise are measured across the same impedance, then the SNR can be obtained by calculating the square of the amplitude ratio:

Each of these techniques employs pseudorandom number sequences — created using pseudorandom number generators — to determine and control the spreading pattern of the signal across the alloted bandwidth.

The relatively high-frequency carrier frequency carrying the signal cannot pass through a power transformer or across the phases of a multiphase system.

In the case of those honey bee species with open combs ( e. g., A. dorsata ), would-be predators are given a warning signal that takes the form of a ' Mexican wave ' which spreads as a ripple across a layer of bees densely packed on the surface of the comb when a threat is perceived, and consists of bees momentarily arching their bodies and flicking their wings.

In its present day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal.

The signal can be reproduced by running the tape back across the tape head, where the reverse process occurs – the magnetic imprint on the tape induces a small current in the read head which approximates the original signal and is then amplified for playback.

This happens as the liquid crystal's polarisation varies in response to an electric control signal applied across it.

In 1963, Smith took his act to the border when the Inter-American Radio Advertising's Ramon Bosquez hired him and sent him to the studio and transmitter site of XERF-AM at Ciudad Acuña in Mexico, a station whose high-powered border blaster signal could be picked up across much of the United States.
