en.wikipedia.org/wiki/Digital_signal

A **digital signal** is a signal that is being used to represent data as a sequence of
discrete values; at any given time it can only take on one of a finite number of
values. This contrasts with an analog signal, which represents continuous values;
at any given time it represents a real number within a continuous range of values.

en.wikipedia.org/wiki/Digital_signal_(signal_processing)

In the context of **digital signal** processing (DSP), a **digital signal** is a discrete-time
signal for which not only the time but also the amplitude has discrete values; in
other words, its samples take on only values from a discrete set (a countable set
that can be mapped one-to-one to a subset of integers). If that discrete set is finite
, ...

A **digital signal** refers to an electrical signal that is converted into a pattern of bits.
Unlike an analog signal, which is a continuous signal that contains time-varying
quantities, a **digital signal** has a discrete value at each sampling point. The
precision of the signal is determined by how many samples are recorded per unit
of ...

**Digital Signals**. **Digital signals** must have a finite set of possible values. The
number of values in the set can be anywhere between two and a-very-large-
number-that's-not-infinity. Most commonly **digital signals** will be one of two values
– like either 0V or 5V. Timing graphs of these signals look like square waves.

**Digital signals** consist of patterns of bits of information. These patterns can be
generated in many ways, each producing a specific code. Modern digital
computers store and process all kinds of information as binary patterns. All the
pictures, text. sound and video stored in this computer are held and manipulated
as patterns ...

Sep 13, 2015 **...** DSP manipulates different types of signals with the intention of filtering,
measuring, or compressing and producing analog signals. Analog signals differ
by taking information and translating it into electric pulses of varying amplitude,
whereas **digital signal** information is translated into binary format where ...
