	Signal (electrical engineering) - Wikipedia, the free encyclopedia
		Signals are often scalar-valued functions of time (waveforms), but may be vector valued and may be functions of any other relevant independent variable.
		It is remarkably useful to analyze the frequency spectrum of a signal.
		For instance, if a signal is passed through an LTI system, the frequency spectrum of the resulting output signal is the product of the frequency spectrum of the original input signal and the frequency response of the system.

	Define signal - a definition from Whatis.com
		The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked.
		Except for DC signals such as telegraph and baseband, all signal carriers have a definable frequency or frequencies.
		Signals also have a property called wavelength, which is inversely proportional to the frequency.

	Signal Transduction
		Signal transduction at the cellular level refers to the movement of signals from outside the cell to inside.
		The movement of signals can be simple, like that associated with receptor molecules of the acetylcholine class: receptors that constitute channels which, upon ligand interaction, allow signals to be passed in the form of small ion movement, either into or out of the cell.
		The signaling pathways utilized by the TGF-b, activin and BMP receptors are different than those for receptors with intrinsic tyrosine kinase activity or that associate with intracellular tyrosine kinases.

	Signal Magazine 1940 - 1945
		Signal was a unique product of Germany's high-powered propaganda machinery: a nearly folio-sized magazine created in an effort to rally other European nations under the Teutonic banner, and to promote and justify German hegemony over Europe.
		In a War of Words, Signal was a most effective weapon which the German propaganda experts succeeded in putting to maximum use.
		For even today the articles of Signal retain their uncanny attractiveness, which is a strong indicator for their dangerous propagandistic qualities.

		This means that signals arriving during long calculations implemented purely in C (such as regular expression matches on large bodies of text) may be delayed for an arbitrary amount of time.

	Revelations on Java signal handling and termination
		Signals can be raised for many different reasons; for example, a SIGSEGV will be raised when a process attempts to access an address for which it does not have permission.
		The JVM's use of signals is platform-dependent; for certain platforms the JVM may use signals for efficient byte code interpretation, or for suspending, resuming, and interrupting threads.
		In this case the JVM signal handler assumes that the signal is for the JVM.

		For instance, the signal’s frequency is drifting by between eight to 37 hertz per second.
		“The signal is moving rapidly in frequency and you would expect that to happen if you are looking at a transmitter on a planet that’s rotating very rapidly and where the civilisation is not correcting the transmission for the motion of the planet,” Korpela says.
		The signal could be an artefact that, for some reason, always appears to be coming from the same point in the sky.

		Cab signal: A signal located in the engineman’s cab or compartment indicating a condition affecting the movement of a train or engine and used in conjunction with interlocking signals and in conjunction with or instead of block signals.
		Grade signal: A permissive signal used along a steep climb and identified by both a number plate and a plate with the letter “G.” The governing rule is usually that a full-tonnage train climbing the grade may pass a grade signal indicating stop without stopping.
		Signal aspect: The appearance of a fixed signal conveying an indication as viewed from the direction of an approaching train, or the appearance of a cab signal conveying an indication as viewed by an observer in the cab.

	Baldwin City Signal: The Signal Oak
		Still, a lantern from the branches of the Signal Oak near Kibbee Cabin telegraphed a code of signs across the Coal Creek Valley to Blue Mound, where they were flashed in turn to Mount Oread at Lawrence and back again.
		The site of Signal Oak, which is marked by a sign and a monument thanks to the work of dedicated local historians, is at the top of Simmons' Hill just north of Baldwin City.
		The farm adjacent to the Signal Oak site on the north is the former Bishop William Quayle's farm that he laughingly called 'my farm that stands on end.' The woods to the north and northwest of this farm are known as the Bridenthal and Rice Natural History Preserves.

	Oilfield Glossary: Term 'X-signal'
		The reactive (X) signal, or that part of the alternating signal at the receiver of an induction logging tool that is out of phase with the transmitter current.
		This signal, also known as the quadrature signal, is less sensitive to formation conductivity and must be separated from the R-signal, which is the main or, in older tools, the only source of the induction log.
		This direct signal is largely eliminated by use of a bucking coil.
