Digital instruments, which necessarily incorporate amplifiers, use the same principles as analog instruments for range resistors.

Digital instruments can be made that either directly measure the time lag between voltage and current waveforms and so calculate the power factor, or by measuring both true and apparent power in the circuit and calculating the quotient.

For most Tandy 1000 models other than the compact EX and HX that did not come already equipped with a hard drive, Tandy offered hard disk options in the form of " hardcards " that were installed in one of the computer's expansion slots and consisted of a controller and drive ( typically a 3. 5 " MFM or RLL unit with a Western Digital controller ) mounted together on a metal bracket.

Digital baseband transmission, also known as line coding, aims at transferring a digital bit stream over baseband channel, typically an unfiltered wire, contrary to passband transmission, also known as carrier-modulated transmission.

Minicomputers, starting with the Digital Equipment Corporation ( DEC ) PDP-8, typically had some way to toggle in short programs by manipulating an array of switches on the front panel.

Digital filters are typically considered in two categories: infinite impulse response ( IIR ) and finite impulse response ( FIR ).

Digital and film cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.

Digital medical images are typically stored locally on a PACS for retrieval.

Digital audio compressed by FLAC's algorithm can typically be reduced to 50 – 60 % of its original size, and decompressed into an identical copy of the original audio data.

Neither AAC nor Dolby Digital Plus codecs are supported by most home AV equipment, which typically accept Dolby Digital or DTS, leaving owners with stereo, rather than surround sound, output.

Digital signal processing algorithms typically require a large number of mathematical operations to be performed quickly and repeatedly on a set of data.

The physical connection is typically RCA connectors or TOSLINK, which transmits a S / PDIF stream carrying either uncompressed digital audio ( PCM ) or the original compressed audio data ( Dolby Digital, DTS, MPEG audio ) to be decoded by the audio equipment.

Digital cable also typically includes a range of audio broadcast services such as Galaxie and Max Trax.

Digital Bodonis typically suffer from a particular kind of legibility degradation.

Digital hardcore music is typically fast and abrasive ; combining the speed, heaviness and attitude of hardcore punk and partly of riot grrrl with electronic music such as hardcore techno, jungle, and industrial rock.

Digital imaging or digital image acquisition is the creation of digital images, typically from a physical scene.

Digital radio broadcasting systems are typically designed for handheld mobile devices, just like mobile-TV systems, but as opposed to other digital TV systems which typically require a fixed directional antenna.

Digital intermediate ( typically abbreviated to DI ) is a motion picture finishing process which classically involves digitizing a motion picture and manipulating the color and other image characteristics.

Digital cable channels typically are allocated above 552 MHz, the upper frequency of cable channel 78.

Such copy-protection is more typically used with very expensive packages and vertical market software, such as CAD / CAM software, MICROS Systems hospitality and special retail software, Digital Audio Workstation applications, and some translation memory packages.

Kazaa, including the domain name, was then sold off to Brilliant Digital Entertainment, Inc. Kazaa now operates as a monthly music subscription service allowing users to download unlimited songs.

More sophisticated cryptographic systems, such as Anonymous Digital credentials, enable users to communicate pseudonymously ( i. e., by identifying themselves by means of pseudonyms ).

Ironically, Sun and AT & T had previously competed over Sun's NFS versus AT & T's Remote File System ( RFS ), and the quick adoption of NFS over RFS by Digital Equipment, HP, IBM, and many other computer vendors tipped the majority of users in favor of NFS.

* users interacting with Digital Items

Digital Items can be considered the kernel of the Multimedia Framework and the users can be considered as who interacts with them inside the Multimedia Framework.

Due to that, we could say that the main objective of the MPEG-21 is to define the technology needed to support users to exchange, access, consume, trade or manipulate Digital Items in an efficient and transparent way.

Similar object code translation techniques were subsequently used by Apple Computers, to move Macintosh software from M68000 machines to PowerPC machines, and by Digital Equipment Corporation, to move VMS users from VAXs to Alpha machines.

The Digital Standards Organization ( DIGISTAN ) states that " an open standard must be aimed at creating unrestricted competition between vendors and unrestricted choice for users.

Intangible Data Products can further be classified into Virtual Digital Goods (" VDG ") that are virtually located on a computer OS and accessible to users as conventional file types, such as JPG and MP3 files, without requiring further application process or transformational work by programmers, and as such the use may be subject to licence and / or rights of digital transfer, and Real Digital Goods (" RDG ") that may exist within the presentational elements of a data program independent of a conventional file type, commonly viewed as 3-D objects or a presentational item subject to user control or virtual transfer within the same visual media program platform.

Digital video does not experience colour bleeding, jitter, or fade, although some users still prefer the analog nature of Hi8 and Super VHS-C, since neither of these produce the " background blur " or " mosquito noise " of digital video compression.

Each CueCat has a unique serial number, and users suspected that Digital Convergence could compile a database of all barcodes scanned by a given user and connect it to the user's name and address.

No lawsuit was ever brought against " hackers ," as this tactic was not employed to go after specific users or the hacker community specifically, but to show " reasonable assertion " that would prevent a corporation from developing integrated software within an operating system or browser which could take over the device and circumvent the CRQ watchdog software and therefore revenue model that Digital Convergence employed.
