SIGNAL USED TO REPRESENT DATA AS A SEQUENCE OF DISCRETE VALUES
Digital (signal); Digital signals; Digital signal (electronics); Logic signal; Binary signal
A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on, at most, 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.

The original image is high-pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low-pass filtered and downscaled, yielding an approximation image; this image is high-pass filtered to produce the three smaller detail images, and low-pass filtered to produce the final approximation image in the upper-left.](https://commons.wikimedia.org/wiki/Special:FilePath/Jpeg2000 2-level wavelet transform-lichtenstein.png?width=200 "An example of the 2D discrete wavelet transform that is used in [[JPEG2000]].

MATHEMATICAL SIGNAL MANIPULATION BY COMPUTERS
Signal sampling; Digital Signal Processing; Digtial Signal Processor; Native processing; DIGITAL SIGNAL PROCESSING; Digital transform; Applications of digital signal processing
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency.

Digital signal controller
HYBRID OF MICROCONTROLLERS AND DIGITAL SIGNAL PROCESSORS
Digital Signal Controller
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
Digital Signal 0
Digital Signal 0 (DS0) is a basic digital signaling rate of 64 kilobits per second (kbit/s), corresponding to the capacity of one analog voice-frequency-equivalent communication channel. The DS0 rate, and its equivalents E0 in the E-carrier system and T0 in the T-carrier system, form the basis for the digital multiplex transmission hierarchy in telecommunications systems used in North America, Europe, Japan, and the rest of the world, for both the early plesiochronous systems such as T-carrier and for modern synchronous systems such as SDH/SONET.
Parallel multidimensional digital signal processing
Parallel multidimensional digital signal processing (mD-DSP) is defined as the application of parallel programming and multiprocessing to digital signal processing techniques to process digital signals that have more than a single dimension. The use of mD-DSP is fundamental to many application areas such as digital image and videoKeimel, Christian, Martin Rothbucher, Hao Shen, and Klaus Diepold.

Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. DS1 is the primary digital telephone standard used in the United States, Canada and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines.
