Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Minnesota Duluth
The University of Minnesota Duluth (UMD) is a public university in Duluth, Minnesota. It is part of the University of Minnesota system and offers 16 bachelor's degrees in 88 majors, graduate programs in 25 different fields, and a two-year program at the School of Medicine and a four-year College of Pharmacy program.The Will and the Way, published by Manley Goldfine and Donn Larson, 2004, chapter 30 by Mike Lalich. History Early history and plans for Duluth Normal School Although the University of Minnesota Duluth did not officially make its appearance until 1947, plans for a college in the Duluth area were first made in the 1890s. The state legislature planned for a teaching school for women (then referred to as a normal school) and in 1895 they passed a bill authorizing the State Normal School at Duluth. In 1896, the City of Duluth donated of land to serve as a foundation for the school, and the state legislature provided additional funds for the construction costs for the ...

Dolby Pro Logic
Dolby Pro Logic is a surround sound processing technology developed by Dolby Laboratories, designed to decode soundtracks encoded with Dolby Surround. Dolby Stereo (also known as ''Dolby MP'' or ''Dolby SVA'') was developed by Dolby in 1976 for analog cinema sound systems. The format was adapted for home use in 1982 as Dolby Surround when HiFi capable consumer VCRs were introduced. It was further improved with the Dolby Pro Logic decoding system after 1987. The ''Dolby MP Matrix'' was the professional system that encoded four channels of film sound into two. This track used by the ''Dolby Stereo'' theater system on a 35mm optical stereo print and decoded back to the original 4.0 Surround. The same four-channel encoded stereo track was largely left unchanged and made available to consumers as ''"Dolby Surround"'' on home video. However, the original Dolby Surround decoders in 1982 were a simple passive matrix three-channel decoder: L/R and Mono Surround. The surround was limite ...

Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek language, Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and i ...

Interstate 35 In Minnesota
Interstate 35 (I-35) is a north–south Interstate Highway that stretches from Laredo, Texas, to Duluth, Minnesota. In the US state of Minnesota, I-35 enters from Iowa and heads north toward the twin cities of Minneapolis and Saint Paul. South of the metropolitan area, I-35 splits into two branches; I-35E runs through Saint Paul and I-35W through Minneapolis. These two branches rejoin north of the Twin Cities, and the highway continues north to Duluth, where it terminates at State Highway 61 (MN 61). The highway was authorized in 1956 and the first segment opened in 1958. It reached Duluth in 1971, and the final segment to east Duluth opened in 1992. Route description I-35 enters the state from Iowa near Albert Lea. It heads roughly due north toward the Twin Cities, where it splits into I-35E and I-35W. The two halves of I-35 rejoin north of the Twin Cities. From there, I-35 travels north-northeast; south of Duluth, it becomes more northeasterly. The route ends ne ...

Duluth Central High School
Duluth Central High School, also known as Central High School, was a secondary school located in Duluth, Minnesota, which educated students in grades ten through twelve until seventh and eighth were added after the closing of Washington Junior High School in 1992. It first opened in 1893 in the original building at the intersection of Lake Avenue and Second Street. The building was officially named Historic Old Central High School on October 19, 2004. In 1971, the new Central High School building was built on top of the hill near the intersection of Central Entrance and Pecan Avenue. This Duluth Central High School closed at the end of the 2010–2011 school year. History When originally built on the hillside in 1892, Duluth Central High School was famed not only for its grand clock tower, which could be seen for miles, but also for its wide halls, sweeping stairways with iron banisters, large chandeliers, and beautiful statuary. Due to age and safety conditions, the Duluth S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Station Identification
Station identification (ident, network ID or channel ID or bumper) is the practice of radio and television stations and broadcast network, networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a "sounder" or "stinger", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding, or a combination of both. As such, it is closely related to production logos, used in television and cinema alike. Station identification used to be done regularly by an announcer at the halfway point during the presentation of a television program, or in between programs. Asia Idents are known as a ''montage'' in Thailand and the Malay world (except Indonesia), and as an ''interlude'' in Cambodia and Vietnam. Philippines Station identifications in the Philippines differ from the vernacular meaning in most of the world. They describe what would be r ...

Simulcast
Simulcast (a portmanteau of simultaneous broadcast) is the broadcasting of programmes/programs or events across more than one resolution, bitrate or medium, or more than one service on the same medium, at exactly the same time (that is, simultaneously). For example, Absolute Radio is simulcast on both AM and on satellite radio. Likewise, the BBC's Prom concerts were formerly simulcast on both BBC Radio 3 and BBC Television. Another application is the transmission of the original-language soundtrack of movies or TV series over local or Internet radio, with the television broadcast having been dubbed into a local language. Early radio simulcasts Before launching stereo radio, experiments were conducted by transmitting left and right channels on different radio channels. The earliest record found was a broadcast by the BBC in 1926 of a Halle Orchestra concert from Manchester, using the wavelengths of the regional stations and Daventry. In its earliest days the BBC often transmit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Range
A broadcast range (also listening range or listening area for radio, or viewing range or viewing area for television) is the service area that a broadcast station or other transmission covers via radio waves (or possibly infrared light, which is closely related). It is generally the area in which a station's signal strength is sufficient for most receivers to decode it. However, this also depends on interference from other stations. Legal definitions The "primary service area" is the area served by a station's strongest signal. The "city-grade contour" is 70 dBμ (decibels relative to one microvolt per meter of signal strength) or 3.16mV/m (millivolts per meter) for FM stations in the United States, according to Federal Communications Commission (FCC) regulations. This is also significant in broadcast law, in that a station must cover its city of license within this area, except for non-commercial educational and low-power stations. The legally protected range of a stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Television
Terrestrial television or over-the-air television (OTA) is a type of television broadcasting in which the signal transmission occurs via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna. The term ''terrestrial'' is more common in Europe and Latin America, while in Canada and the United States it is called ''over-the-air'' or simply ''broadcast''. This type of TV broadcast is distinguished from newer technologies, such as satellite television (direct broadcast satellite or DBS television), in which the signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and U ...

Chisholm, Minnesota
Chisholm is a city in St. Louis County, Minnesota, United States. The population was 4,976 at the 2010 census. The city has been called "The Heart of the Iron Range" due to its location in the middle of the Mesabi Iron Range. History The city was named for its founder, Archibald Mark Chisholm (1862–1933), a mining man and investor from Glengarry County, Ontario, Canada. Chisholm was incorporated in 1901. A post office called Chisholm has been in operation since 1901. With a railroad line to Duluth and plenty of mining work available in and near town, Chisholm's population grew rapidly, and by 1908 it had more than 6,000 people and 500 buildings. On September 5, 1908, a fast-moving forest fire obliterated the town due to dry conditions and the wooden construction of nearly all the town's buildings. Many people escaped by going into the lake. No one died in the fire. Afterward, building codes were enhanced, and by the next summer more than 70 fireproof buildings had been erected ...
