After that point, some stations which affiliated with the network in the weeks before the April 1987 primetime launch, such as Milwaukee's WCGV-TV, signed affiliation agreements on the condition that they would not have to carry The Late Show due to the program's ratings weakness.

The ratings struggles also made it hard for Fox to attract affiliates for their primetime launch on April 5, 1987, and to its disappointment, some prospective affiliates, such as Milwaukee's WCGV-TV, would only sign with the network if they did not have to carry The Late Show.

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

BBC Red Button is broadcast on all digital television platforms in the UK, including digital cable ( DVB-C ), IPTV ( TalkTalk TV – channel 503, no red button or teletext ), digital satellite ( DVB-S ) ( Sky & Freesat ) and digital terrestrial television ( DVB-T ) ( Freeview ).

The channel launched as BBC News 24 on 9 November 1997 at 17: 30 as part of the BBC's foray into digital domestic television channels, becoming the first competitor to Sky News, which had been running since 1989.

Since then, with several relaunches, an increase in funding and resources from the BBC and improvements in digital television technology, the channel has been able to diversify content, with two minute looped bulletins available to view via BBC Red Button, BBC News Online and the BBC's mobile website, alongside individual weather and sport bulletins.

Initially it was difficult to obtain a digital satellite or terrestrial receiver without a subscription to Sky or ONdigital respectively, but now the channel forms an important part of the Freeview package of channels.

With the conversion of the Wenvoe transmitter in Wales to digital on 31 March 2010, Channel 4 became an entirely UK-wide TV channel for the first time.

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.

The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network ( where a bandpass filter limits the frequency range to between 300 and 3400 Hz ), or over a limited radio frequency band.

The aim of digital baseband modulation methods, also known as line coding, is to transfer a digital bit stream over a baseband channel, typically a non-filtered copper wire such as a serial bus or a wired local area network.

The aim of pulse modulation methods is to transfer a narrowband analog signal, for example a phone call over a wideband baseband channel or, in some of the schemes, as a bit stream over another digital transmission system.

These are methods to transfer a digital bit stream over an analog baseband channel ( a. k. a. lowpass channel ) using a pulse train, i. e. a discrete number of signal levels, by directly modulating the voltage or current on a cable.

Episodes of Raynaud's phenomenon sometimes respond to nifedipine or other calcium channel blockers ; severe digital ulceration may respond to prostacyclin analogue iloprost, and the dual endothelin-receptor antagonist bosentan may be beneficial for Raynaud's phenomenon.

The main RFO channel, Télé St. Pierre et Miquelon, is also seen in Canada nationwide on digital cable and satellite, converted to NTSC.

These techniques were available through the open research literature to be used for civilian applications, allowing the creation of digital mobile phone networks with substantially higher channel capacities than the analog systems that preceded them.

Traditional digital methods rely on perturbing noise in the channel file to hide the message, as such, the channel file must be transmitted to the recipient with no additional noise from the transmission.

For this reason many people refer to any 625 / 25 type signal as " PAL " and to any 525 / 30 signal as " NTSC ", even when referring to digital signals, for example, on DVD-Video which don't contain any analog color encoding, thus no PAL or NTSC signals at all.

The 2003 Berkeley report stated that in 2002 alone, " telephone calls worldwide on both landlines and mobile phones contained 17. 3 exabytes of new information if stored in digital form " and that " it would take 9. 25 exabytes of storage to hold all U. S. calls each year.

In the year 1986, merely 1 % of the world's capacity to store information was in digital format, which grew to 3 % by 1993, 25 % in the year 2000, and exploded to 97 % of the world's storage capacity by 2007.

For example, in North America, " channel 2 " refers to the broadcast or cable band of 54 to 60 MHz, with carrier frequencies of 55. 25 MHz for NTSC analog video ( VSB ) and 59. 75 MHz for analog audio ( FM ), or 55. 31 MHz for digital ATSC ( 8VSB ).

In 1976, another digital audio tape format was developed by Soundstream, using 1 inch ( 25. 4 mm ) wide reel-to-reel tape loaded on an instrumentation recorder manufactured by Honeywell acting as a transport, which in turn was connected to outboard digital audio encoding and decoding hardware of Soundstream's own design.

The study employed digital particle imaging velocimitry to capture the bird ’ s wing movements on film, which enabled the discovery that the hummingbird ’ s hovering is achieved due primarily to its wing ’ s downstroke ( which accounts for 75 % of its lift ) rather than its upstroke ( which makes up the additional 25 % of the lift ).

In addition to over 650, 000 print volumes and a large collection of media resources, it provides access to more than 25, 000 electronic and print journals, a large number of e-books, databases, and other digital information resources.

Companies and individual users could connect in to the PSS network using the full X. 25 interface, via a dedicated four-wire telephone circuit using a PSS analog modem and later on, when problems of 10-100ms transmission failures with the PCM Voice based transmission equipment used by the early Kilostream service were resolved, via a Kilostream digital access circuit ( actually a baseband modem ).

The Centris 660AV uses a 25 MHz 68040 and also includes a digital signal processor chip from AT & T.

The first input / output interface was a 25 pin parallel cable ( SMPTE 125M ) and later updated to serial digital interface on coaxial cable ( SDI, SMPTE 259M, 75Ω coax, 270 MHz ).

With the advent of digital presses made by such companies as Canon, Kodak, Ricoh and Xerox, it became practical in the 1990s to print full-color menus affordably in short press runs, sometimes as few at 25 menus.

More recently, the advent of the Xerox iGen3 digital press allows sheet sizes of 14. 25 x 22. 5 inches ( 36 x 57 cm ), offering the option of larger laminated menus in press runs of as few as 100 copies.

Today, WGBH-TV's and WGBX-TV's transmitters are located at the CBS digital television facility in Needham, Massachusetts, where channel 44 first transmitted on September 25, 1967 ; channel 2 moved there on June 18, 1966.

Although artists working with other media have expressed interest in the concept, such as Roy Ascott, " cyberspace " in digital art is mostly used as a synonym for immersive virtual reality and remains more discussed than enacted.
