Definitions for "signal"
A sign made for the purpose of giving notice to a person of some occurence, command, or danger; also, a sign, event, or watchword, which has been agreed upon as the occasion of concerted action.
To notify by a signals; to make a signal or signals to; as, to signal a fleet to anchor.
Software interrupts sent to a program to indicate that an important event has occurred. The events can vary from user requests to illegal memory access errors. Some signals, like the interrupt signal, indicate that a user has asked the program to do something that is not in the usual flow of control.
Of or pertaining to signals, or the use of signals in conveying information; as, a signal flag or officer.
The event or phenomenon that conveys data from one point to another.
(1) Analog or digital information being transported via electrons, photons, or electromagnetic waves respectively through copper (twisted pair or coax), fiber, or the airwaves. (2) The act of transporting his information. (3) The act of sending control information to or from a telephone switch to set up, manage or tear down calls. Analog signaling methods for voice circuit-switched calls include dial pulse (from a rotary dial) and touch tone.
A token; an indication; a foreshadowing; a sign.
Means of controlling the movement of trains by warning or advising the engineer of the occupational state of the line ahead or intention to divert to another line.
visual indication given to a train driver advising the speed, direction or route of the train. Types: hand signals, semaphore (flag) signals, cab signals and light signals.
communicate silently and non-verbally by signals or signs; "He signed his disapproval with a dismissive hand gesture"; "The diner signaled the waiters to bring the menu"
I noticed warning signals/signs about my health.
1. A sign given by gesture, red flag, flashing lights, warning sound, etc. used to convey a command, direction, warning, etc. 2. A sign, understood to be the occasion for a prearranged combined action. 3. Indicator which gives an alert that a device is in operation.
Any carrier of information; opposed to noise. See carrier wave.
The measured value recorded by a pixel during a CCD integration. The signal in a CCD image usually comprises input from sky, thermal, and electronic sources. The natural degree of randomness in the pixel value is the noise component of the signal.
THAT PART OF THE VARIATION OF THE ENVIRONMENT WHICH CORRESPONDS TO A REAL - PHYSICAL PHENOMENON. WHEN THE SIGNAL IS LARGE - ITS SIGNATURE STANDS OUT ABOVE THE REMAINDER TO THE VARIATION OF THE ENVIRONMENT - CALLED THE NOISE. SIGNAL IS SOMETIMES PREDICTABLE. NOISE IS NOT. THE RELATIONSHIP BETWEEN SIGNAL AND NOISE IS EXPRESSED AS A NUMBER - CALLED THE SIGNAL-TO-NOISE RATIO OR S/N. WHEN S/N IS GREATER THAN 1 - SIGNAL IS LARGER THAN NOISE - AND THE SIGNATURE OF THE DISTURBANCE CAUSING THE SIGNAL CAN BE SEEN. WHEN S/N IS LESS THAN 1 WE HAVE NO HOPE OF SEEING OR PREDICTING THE DISTURBANCE.
The act of signalling the completion of a request. See also: asynchronous request
a specification of an asynchronous stimulus communicated between instances
a specification of type of send request instances communicated between objects
(noun) - An object to which callback slots can be connected. When the signal is emitted, each callback will be invoked. The signal and the connected slots have a specific return type and parameter types.
a callback container that can store any number of references to different callback targets
a list of slots that are executed on emission
Noticeable; distinguished from what is ordinary; eminent; remarkable; memorable; as, a signal exploit; a signal service; a signal act of benevolence.
notably out of the ordinary; "the year saw one signal triumph for the Labour party"
an ordinary protected method
In Rail3D signals control traffic, as on the prototype. The visual model of the signal can be made to represent different localised signal systems.
In studies of the auditory system, a signal is any sound entering the auditory system and its various transduced forms within the auditory system. Such a signal can therefore be an acoustic signal (up to the tympanic membrane), a mechanical vibratory signal (from the tympanic membrane to the Organ of Corti), or a neural signal (from the Organ of Corti to the Auditory Cortex). Most signals within the auditory system represent only part of the original acoustic signal (eg. individual auditory nerve fibres represent their characteristic frequencies.
a message that an object wants to broadcast
A named event that can be explicitly invoked ("raised"). Signals may have parameters. A signal may be broadcast or directed toward a single object or a set of objects.
The images and sounds broadcast from a station. Current analog broadcast TV stations are divided, according to signal strength, between VHF (very high frequency) stations, with a channel position of 2 to 13, and UHF (ultra high frequency) stations, 14 and above. The reach and extent of over-the-air broadcast signals traditionally have been grouped by broadcasters and the FCC under the headings of "Grade A" and "Grade B": "Grade A" is that most highly concentrated area of a station's signal, closest to its broadcast tower; "Grade B" is its extended and progressively weaker area of coverage.
To communicate by signals; as, to signal orders.
1) a special system of agreed meanings to cards played by defenders in order to communicate their holdings to each other. 2) A particular play with such a meaning.
A message from one task to another, which is used in the UNIX signaling system. The Tera operating system defines a set of signals identified by number that it may deliver to a task. The source of a signal could be the operating system, the hardware, another task, or a task may send a signal to itself. For each signal, the system defines a default action to take when a program receives a signal. Additionally, a program may install its own signal handler that executes in response to a signal.

Signal is a cartoon frog with a GPS antenna on his head and is the official mascot of geocaching.com.
Another name for vacuum transmitted from one location in the carburetor to another. For example, a vacuum signal from the low-pressure venturi area to the float bowl, which is referenced to atmospheric pressure, initiates main circuit fuel flow.ySignal amplifierzƒu[ƒXƒ^ƒxƒ“ƒ`ƒ…ƒŠ‚̂悤‚ɃoƒLƒ…[ƒ€‚ðŠg‘å‚·‚é‚à‚ÌB

A general term for audio as it travels through audio cables and equipment.
An audio or display response alerting the operator that a target has been detected.
detectable physical quantity.
A continuously varying function of time that is approximated by discrete samples.
a class member function that is undefined at compile time
a function of time, which means that it can be a varying entity with several variables, which must include time. As an example, a 2D image can be represented by a function g(x,y,t), where x and y are the co-ordinates on the image's plane, and t is the instant of observation. The function's value is the amplitude of the signal. This lesson only considers signals varying with time - one-dimensional signals. Theoretically, the signals can be classified as continuous or discrete.

an off input of path P if it is an input to a gate in P but it is not an on input
