Exile turns the Electron's one channel output into a digital speaker for PCM output.

The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file.

The output of a linear digital filter to any given input may be calculated by convolving the input signal with the impulse response.

Class-D and class-E amplifiers are sometimes mistakenly described as " digital " because the output waveform superficially resembles a pulse-train of digital symbols, but a class-D amplifier merely converts an input waveform into a continuously pulse-width modulated ( square wave ) analog signal.

This can be accomplished by using a generator that generates both black burst and video-resolved word clock, or by synchronizing the master digital device to video, and synchronizing all subsequent devices to the word clock output of the master digital device ( and to LTC ).

It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output.

When placed on the external address bus, it replicates the original functions of B and C. Port A has input capture, output compare, pulse accumulator, and other timer functions ; port D has serial I / O, and port E has an analog to digital converter ( ADC ).

The PLC uses a digital output to open the inlet valve to fill the tank.

The line output of a teleprinter can be at either digital logic levels (+ 5 V signifies a logical " 1 " or mark and 0 V signifies a logical " 0 " or space ) or line levels (- 80 V signifies a " 1 " and + 80 V a " 0 ").

The amplified electrical signal output by the photomultiplier is displayed as a two-dimensional intensity distribution that can be viewed and photographed on an analogue video display, or subjected to analog-to-digital conversion and displayed and saved as a digital image.

Typically the digital output will be a two's complement binary number that is proportional to the input, but there are other possibilities.

# A comparator is designed to produce well limited output voltages that easily interface with digital logic.

The output is a binary state often used to interface real world signals to digital circuitry ( see analog to digital converter ).

When the voltages are nearly equal, the output voltage will not fall into one of the logic levels, thus analog signals will enter the digital domain with unpredictable results.

In a continuously variable slope delta ( CVSD ) modulation converter, the mean proportion of binary " 1 " digits at the converter output in which each " 1 " indicates a run of a specified number of consecutive bits of the same polarity in the digital output signal.

In LTI system theory, control theory, and in digital or analog signal processing, the relationship between the input signal,, to output signal,, of an LTI system is governed by the convolution operation:

* Amplifiers and attenuators in output fibers that adjust the signal to the digital “ 0 ” power range ( when the fiber is not switched to ) or to the normal power range when it is ( e. g., ).

In high speed digital transmission, pre-emphasis is used to improve signal quality at the output of a data transmission.

As many as ten digital switches may be named and provided by the DSW statement for consideration by the SETSW and logic macro-instructions.

Therefore as analog signal processing systems become more complex, they may ultimately degrade signal resolution to such an extent that their performance is surpassed by digital systems.

Another advantage with analog signals is that their processing may be achieved more simply than with the digital equivalent.

An analog signal may be processed directly by analog components, though some processes aren't available except in digital form.

As audio signals may be electronically represented in either digital or analog format, signal processing may occur in either domain.

Authors may post the documents on their own websites, but they are required to link back to the digital library's reference page for the paper.

The International System of Units does not define units for digital information but notes that the SI prefixes may be applied outside the contexts where base units or derived units would be used.

When information is stored in digital systems, collation may become an automated process.

A checksum or hash sum is a fixed-size datum computed from an arbitrary block of digital data for the purpose of detecting accidental errors that may have been introduced during its transmission or storage.

A broadcaster may opt to use a standard-definition ( SDTV ) digital signal instead of an HDTV signal, because current convention allows the bandwidth of a DTV channel ( or " multiplex ") to be subdivided into multiple digital subchannels, ( similar to what most FM radio stations offer with HD Radio ), providing multiple feeds of entirely different television programming on the same channel.

A digital filter may be described in the z plane by its characteristic collection of zeroes and poles.

Depending on the requirements of the application, digital signal processing tasks can be implemented on general purpose computers ( e. g. supercomputers, mainframe computers, or personal computers ) or with embedded processors that may or may not include specialized microprocessors called digital signal processors.

Data from digital motion picture cameras may be converted to a convenient image file format for work in a facility.

When all of the sound, picture, and data elements of a production have been completed, they may be assembled into a Digital Cinema Distribution Master ( DCDM ) which contains all of the digital material needed for projection.

To implement such controllers electrical engineers may use electrical circuits, digital signal processors, microcontrollers and PLCs ( Programmable Logic Controllers ).

For digital signals, signal processing may involve the compression, error detection and error correction of digitally sampled signals.

Ironically, the answer to the outdated mentor may be digital collaboration with worldwide mentor webs ; composed of individuals with creative ideas for the classroom.

These days analog circuitry may use digital or even microprocessor techniques to improve performance.

Sometimes it may be difficult to differentiate between analog and digital circuits as they have elements of both linear and non-linear operation.

No optimism is more baseless than that which believes that the high speed of modern digital computers allows for use of the crudest of methods in searching out a result.

An example of a digital remote telescope operation for public use via the Internet is the The Bareket Observatory.

This explains the widespread use of digital signals in preference to analog in modern technology.

The song " The Raven " featured lead vocals by the actor Leonard Whiting, and, according to the 2007 remastered album liner notes, was the first rock song to use a digital vocoder, with Alan Parsons speaking lyrics through it.

Although such a conversion can be prone to loss, most modern audio systems use this approach as the techniques of digital signal processing are much more powerful and efficient than analog domain signal processing.

Many dual system television receivers, equipped to receive both analog transmissions and digital transmissions have analog tuner ( television ) receiving capability and must use a television antenna.

On slower or congested links ( 622 Mbit / s and below ), ATM does make sense, and for this reason most asymmetric digital subscriber line ( ADSL ) systems use ATM as an intermediate layer between the physical link layer and a Layer 2 protocol like PPP or Ethernet.

It had simple digital joysticks and was almost fully backward-compatible with the Atari 2600, the first console to have backward compatibility without the use of additional modules.

This digital signature code is not present in PAL 7800s, which use various heuristics to detect 2600 cartridges, due to export restrictions.

After that point, however, most cellular companies were eager to shut down AMPS and use the remaining channels for digital services.

Digital ammeter designs use an analog to digital converter ( ADC ) to measure the voltage across the shunt resistor ; the digital display is calibrated to read the current through the shunt.

The use of 8-bit codes for digital telephony also caused 8-bit data octets to be adopted as the basic data unit of the early Internet.

The use of a Polaroid camera was standard but has since been replaced by the advent of digital cameras.

Computer displays and televisions with CRTs driven by digital electronics often use refresh rates of 100 Hz or more to largely eliminate any perception of flicker – see flicker-free.

In March 1974, during a meeting of the audio group, two engineers from the Philips research laboratory recommended the use of a digital format on the 20 cm optical disc, because an error-correcting code could be added.

Digital video and digital still photography systems sometimes use a luma / chroma decomposition for improved compression.

Computer music systems and approaches are now ubiquitous, and so firmly embedded in the process of creating music that we hardly give them a second thought: computer-based synthesizers, digital mixers, and effects units have become so commonplace that use of digital rather than analog technology to create and record music is the norm, rather than the exception.

A variant of Coral 66 was developed during the late 1970s / early 1980s by the British GPO, in conjunction with GEC, STC and Plessey, for use on the System X digital telephone exchange control computers, known as PO-CORAL.

They would start by selling computer modules as stand-alone devices that could be purchased separately and wired together to produce a number of different digital systems for lab use.
