Fernmeldeturm Nürnberg
The Fernmeldeturm Nürnberg, the tallest structure in Bavaria, is a telecommunication tower in Nuremberg, southern Germany. Also called the ''Nürnberger Ei'' ("Egg of Nuremberg") because of its egg-shaped tower basket in a height of 185 metres, it is 292 metres high and was built between 1977 and 1980 according to blueprints by architect Erwin Heinle. The tower basket accommodates transmission mechanisms for Frequency modulation, DAB, UMTS, pager, amateur radio and a microwave radio relay link and – closed since 1991 – a rotating restaurant and a prospect platform. Responsible operator is the DFMG Deutsche Funkturm (German radio tower) GmbH, a subsidiary of Deutsche Telekom based in Münster. From 22 January 2003 to 4 April 2003 the Nürnberg telecommunication tower also served for the spreading of the program of megaradio on mediumwave frequency 945 kHz. For this a wire antenna was strung along the tower shaft, from the top of the tower to the roof of an operating b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Wave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ProSieben
ProSieben (, ''sieben'' is German for "seven"; often stylized as Pro7) is a German free-to-air television network owned by ProSiebenSat.1 Media. It was launched on 1 January 1989. It is Germany's second-largest privately owned television company. Although ProSieben produces some of its programming itself, it also airs many American imports. On 3 May 2012, the network launched a pay-TV channel called ProSieben Fun. A third channel called ProSieben Maxx started broadcasting on 3 September 2013. The three different feeds of the channel are: ProSieben (for Germany), ProSieben Austria (for Austria), and ProSieben Schweiz (for Switzerland and Liechtenstein). The main difference is that they have different advertisements and news for each target country. The channel uses an English slogan: "We love to entertain you." ProSieben broadcasts from the Astra 1L and 3A satellites and is uplinked by MX1 (now part of SES Video). History 1988–1993 On 13 October 1988, ProSieben T ...

3sat
In logic and computer science, the Boolean satisfiability problem (sometimes called propositional satisfiability problem and abbreviated SATISFIABILITY, SAT or B-SAT) is the problem of determining if there exists an interpretation that satisfies a given Boolean formula. In other words, it asks whether the variables of a given Boolean formula can be consistently replaced by the values TRUE or FALSE in such a way that the formula evaluates to TRUE. If this is the case, the formula is called ''satisfiable''. On the other hand, if no such assignment exists, the function expressed by the formula is FALSE for all possible variable assignments and the formula is ''unsatisfiable''. For example, the formula "''a'' AND NOT ''b''" is satisfiable because one can find the values ''a'' = TRUE and ''b'' = FALSE, which make (''a'' AND NOT ''b'') = TRUE. In contrast, "''a'' AND NOT ''a''" is unsatisfiable. SAT is the first problem that was proved to be NP-complete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arte
Arte (; (), sometimes stylized in lowercase or uppercase in its logo) is a European public service channel dedicated to culture. It is made up of three separate companies: the Strasbourg-based European Economic Interest Grouping ARTE, plus two member companies acting as editorial and programme production centres, ARTE France in Paris (formerly known as La Sept) and ARTE Deutschland in Baden-Baden (a subsidiary of the two main public German TV networks ARD and ZDF). As an international joint venture (an EEIG), its programmes focus on audiences in both countries. Because of this, the channel has two audio tracks and two subtitle tracks, one each in French and German. 80% of Arte's programming is provided by its French and German subsidiaries, each making half of the programmes. The remainder is provided by the European subsidiary and the channel's European partners. Selected programmes are available with English, Spanish, Polish and Italian subtitles online. In January ...

Phoenix (German TV Station)
Phoenix (stylised as ) is a German free-to-air television channel which is operated jointly by public-service broadcasters ARD and ZDF. It broadcasts documentaries, news, special events coverage and discussion programmes. Phoenix's headquarters are in Bonn, the former West German capital. On November 15th 2022, Phoenix closed its SDTV feed across its cable and satellite feeds, but the SD feed can still be received via an antenna. Programming Phoenix broadcasts a deaf-subtitled version of the Tagesschau, ARD's flagship news broadcast, and ZDF's premier news broadcast Heute-Journal, in German Sign Language. The channel's flagship news broadcast is ''Der Tag'' ("The Day"), which airs from 11:00 pm to midnight. Its length enables extended reports and interviews to be included. The show ''Vor Ort'' ("On Scene") includes live coverage of political events, public lectures by important personalities, press conferences and assemblies of the Bundestag and Bundesrat. Daily ta ...

Das Erste
Das Erste (; "The First") is the flagship national television channel of the ARD association of public broadcasting corporations in Germany. ''Das Erste'' is jointly operated by the nine regional public broadcasting corporations that are members of the ARD. The channel was officially launched on 25 December 1952 as ''NWDR-Fernsehen'' and renamed to ''Deutsches Fernsehen'' in 1954. Since 1996, the official brand is ''Das Erste''; the full name Erstes Deutsches Fernsehen (''First German Television'') is still used before every major news edition. In colloquial speech, the station is usually called ''Erstes Programm'' ("First Channel"), or by its metonym, ''ARD''. History The channel's first experimental broadcast was on 27 November 1950 as the TV channel of the then NWDR, which in 1956 split into NDR and WDR. The regular NWDR television service started on 25 December 1952. Nationwide transmission began on 1 November 1954 within the ARD framework, under the name ''Deutsches ...

Polarization (waves)
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string ''(see image)''; for example, in a musical instrument like a guitar string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string. In contrast, in longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization. Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, and transverse sound waves (shear waves) in solids. An electromagnetic wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DVB-T
DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in Singapore in February, 1998. This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation. It is also the format widely used worldwide (including North America) for Electronic News Gathering for transmission of video and audio from a mobile newsgathering vehicle to a central receive point. It is also used in the US by Amateur television operators. Basics Rather than carrying one data carrier on a single radio frequency (RF) channel, COFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulates a set of closely spaced adjacent sub-carrier frequencies. In the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
