FM Broadcasting
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

Morrison Hotel (Chicago)
The Morrison Hotel was a high rise hotel at the corner of Madison and Clark Streets in the downtown Loop community area of Chicago, Illinois. It was designed by the architectural firm of Holabird & Roche and completed in 1925. The hotel was demolished in 1965 to make room for the First National Bank Building (now Chase Tower). The hotel was named for Orsemus Morrison, the first coroner in Chicago, who bought the site in 1838 and in 1860 built a three-story hotel with 21 rooms. Destroyed in the Great Chicago Fire of 1871, this was replaced by an eight-story building. In 1915 Harry C. Moir, who had bought the property from Morrison's nephew, built a 21-floor, 500-room hotel designed by Marshall and Fox. The hotel was expanded by 650 rooms in 1918. In 1925 the firm Holabird & Roche further expanded it, adding a 46-story tower. The hotel had 1,800 rooms in 1931. A fourth, 21-story section was then added, bringing the number of rooms to 2,210, but was sold in 1937, becoming the H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Tribune
The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing. Founded in 1847, and formerly self-styled as the "World's Greatest Newspaper" (a slogan for which WGN radio and television are named), it remains the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region. It had the sixth-highest circulation for American newspapers in 2017. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the Republican Party's progressive wing. In the 20th century under Medill's grandson, Robert R. McCormick, it achieved a reputation as a crusading paper with a decidedly more American-conservative anti-New Deal outlook, and its writing reached other markets through family and corporate relationships at the ''New York Daily News'' and the ''Washington Times-Herald.'' The 1960s saw its corporate parent owner, Tribune Company, rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chesterton, Indiana
Chesterton is a town in Westchester, Jackson and Liberty townships in Porter County, in the U.S. state of Indiana. The population was 14,241 at the 2020 Census. The three towns of Chesterton, Burns Harbor, and Porter are known as the Duneland area. Etymology The name Chesterton comes from its township, with Chester deriving from Westchester and the -ton suffix denoting it as a town. History Chesterton was first settled under the name Coffee Creek in 1833, with its post office being established in 1835. The post office would eventually be renamed to Calumet in 1850, as which the town was platted when the railroad was extended to that point in 1852. Due to a town on the same railroad also being named Calumet, the name would finally be changed to Chesterton in 1870 and it was reincorporated as a town in 1899 after a failed incorporation in 1869, with its population of 788 being the second-largest in Porter County at the time. In 1933, a United Airlines NC13304 flight became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User-generated Content
User-generated content (UGC), alternatively known as user-created content (UCC), is any form of content, such as images, videos, text, testimonials, and audio, that has been posted by users on online platforms such as social media, discussion forums and wikis. It is a product consumers create to disseminate information about online products or the firms that market them. User-generated content is used for a wide range of applications, including problem processing, news, entertainment, customer engagement, advertising, gossip, research and many more. It is an example of the democratization of content production and the flattening of traditional media hierarchies. The BBC adopted a user-generated content platform for its websites in 2005, and TIME Magazine named "You" as the Person of the Year in 2006, referring to the rise in the production of UGC on Web 2.0 platforms. CNN also developed a similar user-generated content platform, known as iReport. There are other examples of news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Repeater
In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate. There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station is a repeater used in broadcast radio and television. Overview When an information-bearing signal passes through a communication channel, it is progressively degraded due to loss of power. For example, when a telephone call passes through a wire telephone line, some of the powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Subchannels
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analog Transmission
Analog transmission is a transmission method of conveying information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that information. It could be the transfer of an analog signal, using an analog modulation method such as frequency modulation (FM) or amplitude modulation (AM), or no modulation at all. Some textbooks also consider passband data transmission using a digital modulation method such as ASK, PSK and QAM, i.e. a sinewave modulated by a digital bit-stream, as analog transmission and as an analog signal. Others define that as digital transmission and as a digital signal. Baseband data transmission using line codes, resulting in a pulse train, are always considered as digital transmission, although the source signal may be a digitized analog signal. Methods Analog transmission can be conveyed in many different fashions: * Optical fiber * Twisted pair or coaxial cable * Radio * Underwater acoustic communication There a ...
