a visual, audible, electrical or other indication used to convey information.
Electrical representation of an input such as a sound wave.
This is an electric quantity (i.e., voltage, current or field strength) sent from a source to a receiver whose modulation represents a data transmission.
Refers to an electrical current present on a wire or in a circuit which represents a soundwave. The electrical representation of the sound going down the wires from one piece of equipment to another.
It is an electrical quantity or effect, such as current, voltage, or electromagnetic waves, which can be varied in such a way so as to convey information.
In electronics, the information contained in electrical quantities of voltage or current that forms the input, timing, or output of a device, circuit, or system.
an electric quantity (voltage or current or field strength) whose modulation represents coded information about the source from which it comes
a form of energy in which information is conveyed
a function that conveys information, generally about the state or behavior of a physical system
a mechanical or electrically operated device
An electrical current that is passed from one component to another.
A sound wave, transmitted as an electrical waveform or its digital representation.
An electrical impulse of specified voltage, current, polarity, and pulse width.
A varying electrical voltage that represents sound.
Any electronic visual, audible, or other indication used to convey information. In semiconductors, an electrical quantity (typically voltage, current, or light level) corresponding to some physical quantity. Signals are coded in frequency or amplitude to separate them from unwanted noise.
information carried in some medium, often a waveform
An electrical impulse. First popularized by Paul Revere.
The effect (such as pulse of electromagnetic energy) conveyed over a communication path or system. Signals are received by the sensor from the scene and converted to another form for transmission to the processing system.
Electrical information that can be transmitted through wires or by electromagnetic waves.
1) In audio, an alternating current (or voltage) matching the waveform of, or being originally obtained from a sound pressure wave. 2) Also in audio, an alternating current (or voltage) between 20 Hz and 20,000 Hz. 3) A digital audio bit stream.
A database object that represents a scalar, logical entity that connects one or more member instance terminals. A scalar net is equivalent to a signal. Ties together all the nets that implement the signal. Can belong to a number of different nets. See also wire .
Electrical energy which is made to vary, overtime, in a controlled manner.
Any visible or audible indication which can convey information. Also, the information conveyed through a communication system.
An electrical transmittance (either input or output) that conveys information.
A physical, time-dependent energy value used for the purpose of conveying information through a transmission link.
the desired portion of electrical information.
A generated electrical impulse that is a change in voltage to trigger or monitor an event.
An information conveying current, including digital, analog, audio and video information.
Any series of electrical impulses or electromagnetic waves that represent information.
A data stream that comes from electrical impulses or electromagnetic waves.
The audible, repeated pulse from a radio transmitter.
A variation in an electrical current that represents pressure changes (sound). Most audio signals are alternating currents, reversing direction according to how often the signal crosses zero level.
In electronics, a signal is an electric current or electromagnetic field used to convey data from one place to another. 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. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams.
A current used to convey information, either digital, analog, audio or video.
Detectable transmitted energy that can be used to carry information. As applied to electronics, any transmitted electrical impulse.
Any electrical transmittance that conveys data.
A signal is a time-dependent value that is attached to a propagating phenomenon (energy related)that is used to convey information. An example of a signal could be a soulnd or audio signal whereby the data is characterized by its pitch or loudness.
Electrical quantity that conveys information.
An analog or digital data that convey information.
In the fields of communications, signal processing, and in electrical engineering more generally, a signal is any time-varying quantity. Signals are often scalar-valued functions of time (waveforms), but may be vector valued and may be functions of any other relevant independent variable.
In biology a signal or biopotential is an electric quantity (voltage or current or field strength), caused by chemical reactions of charged ions. Another use of the term lies in describing the transfer of information between and within cells, as in signal transduction. Biological signals can also be seen as an example of signal (information theory).
A signal within the context of circuit theory is any information that has value to a particular electronic network. In a more concrete sense, the signals in a circuit are carried as changes in the voltages and currents of the circuit over time. Signals in circuit theory come in two types: analog and digital.
