an electrical or optical signal that varies in discrete steps; electrical signals are coded as voltages; optical signals are coded as pulses of light
A signal that is sent and received in discrete intervals. An analog signal-is a signal that varies continuously over time rather than being sent and received in discrete intervals.
Your computers data signal is in digital form and is made up of 0 and 1 - or 'on' and 'off' if you like. The modem, which is the device between your computer and your phone line, converts this digital signal into an analogue signal, and back again on its return, so that it can travel along the phone line.
A discontinuous signal. One whose state consists of discrete elements...representing very specific information.
Signal represented by a sequence of binary bits representing ones and zeros.
Electronic signals that are transmitted as in strings of 1s and 0s. (See also analog signal.)
A sequence of binary bits that represent ones and zeros makes up a digital signal.
(1) A nominally discontinuous electrical signal that changes from one state to another in discreet steps. (2) A signal that is time-wise discontinuous (i.e., discreet) and can assume a limited set of values. Antonym: analog.
A signal that has only two distinct states: off and on.
A signal whose level has only discrete values, like on or off, 1 or 0, +5v or +0.2v.

Representation of information by a set of discrete values in accordance with a prescribed law. These values are represented by numbers.
a form of information transmission in which the signal varies in discrete steps, not in a continuous manner.
A signal that is composed of two energy levels (on and off). Digital signals are used by computers to transmit data. The patterns of the level changes represents individual bits of information.
A digital signal has one of two different values. These are often represented by on and off, or by 1 and 0. Systems

A discrete or discontinuous electrical signal composed of a series of on and off pulses, representing binary digits (ones and zeros).
A signal measurement over time that consists of separate, discrete values generally with a constant sampling time interval.
An electronic signal where every different value from the real-life excitation (sound, light) has a different value of binary combinations (words) that represent the analog signal.
Digital (data signal) information represented by ones and zeros and is interpreted by a computer. Digital networks have less noise than analog networks.
A discrete signal with two operational states, typically On and Off.
A digital signal is strung together in infinite variations at rapid speeds to transmit computer information. Most projectors utilize analog signals today whether it be from component, composite or RGB cables.
An analogue signal that has been converted to a digital form so that it can be processed by a microprocessor.
A signal with only two values, normally 0 and 1, during transmission, unlike an analog signal whose values constantly vary.
An electrical signal that is comprised of a stream of digits utilizing only two voltage levels representing either "ON (1)" or "OFF (0)". Whereas analog signals are dependant on the amount of voltage at any given time, digital signals are defined by only the presence or absence of voltage.
A signal that is comprised of binary information, i.e. 1 or 0, to allow processing by microprocessor based equipment.
Digital Signal: Binary data bit-codes with only two values, either 1 or 0, ON or OFF. They can be strung together in infinite variations at rapid speeds to transmit computer information.
A signal consisting only of marks & spaces or 1's and 0's
A way of sending voice, video, or data that reconstructs the signals using binary codes (1s and 0s) for transmission through wire, fiber optic cable, videoconference, or over air techniques. Digital audio/video signals represented by discrete variations (in voltage, frequency, amplitude, location, etc.) can be transmitted faster and more accurately than analog signals.
A control signal that is either on of off (e.g., fan start/stop).
A signal that uses a stream of binary data (On and Off signals) to transmit the color intensity of a pixel.
A discrete signal which can only take on one of several (usually only two) discrete levels in contrast to analog signals which can take a continuous range of levels.
A digital signal (electrical or otherwise) is a signal in which information may be carried in a limited (two or more) number of different discrete states. Probably the most fundamental and actually widely used form of digital signal is binary. This is where one amplitude condition represents a binary.
An electronic signal that is coded in binary format (0s and 1s) and uses electronic or optical pulses as opposed to an analog signal that uses a continuously variable flow.
Representing bit patterns as on or off electrical voltages.
See Analog vs. Digital Signal.
A discrete or discontinuous signal whose various states are discrete intervals apart, such as +15 volts and -15 volts.
Unlike its analog counterpart, a digital signal is not a continuously variable and varying signal. It only assumes a finite number of discrete values, and bits, in 1s and 0s, represent digital information.
An electrical signal which possesses two distinct states (on/off, positive/negative); typically represented by "0" or "1".
A discrete or discontinuous signal; one whose various states are identified with discrete levels or values.
A signal that has only two (on or off, 1 or 0) possible values. 2. A discrete or discontinuous signal, one whose various states are discrete intervals apart.
A signal whose units are represented by either one of only two states: on or off, yes or no, 1 or 0. Since no gradations in between are permitted, digital signals are precise, unambiguous, and quite immune to noise. See also analog.
Signal that takes on only two values, off or on, typically represented by “0” or “1.” Digital signals require less power but (typically) more bandwidth than analog, and copies of digital signals can be made exactly like the original.
Is a signal defined by patterns of binary impulses of electrons. Some examples of digital signals are EIA, NRZ-L, NRZI, and HDLC.
A signal in which information is carried in a limited number of different discrete states. The most fundamental and widely used form of digital signals are binary signals, in which one amplitude condition represents a binary digit 1, and another amplitude condition represents a binary digit 0.

A signal that varies only at regular time intervals and has one, two, or more predetermined amplitudes for each interval.
A signal that has a limited number of discrete states prior to transmission. This may be contrasted with an analog signal which varies in a continuous manner and may be said to have an infinite number of states.

A signal that transfers information by transmitting a series of bits (on and off levels or "1" and "0").
The term digital signal is used to refer to more than one concept. It can refer to discrete-time signals that are digitized, or to the waveform signals in a digital system.
