Carrier Current
Carrier current transmission, originally called wired wireless, employs guided low-power Radio frequency, radio-frequency signals, which are transmitted along electrical conductors. The transmissions are picked up by receivers that are either connected to the conductors, or a short distance from them. Carrier current transmission is used to send audio and telemetry to selected locations, and also for low-power broadcasting that covers a small geographical area, such as a college campus. The most common form of carrier current uses longwave or medium wave Amplitude modulation, AM radio signals that are sent through existing electrical wiring, although other conductors can be used, such as telephone lines. Technology Carrier current generally uses low-power transmissions. In cases where the signals are being carried over electrical wires, special preparations must be made for distant transmissions, as the signals cannot pass through standard utility transformers. Signals can bridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downers Grove
Downers Grove is a village in DuPage County, Illinois, United States. It was founded in 1832 by Pierce Downer, whose surname serves as the eponym for the village. Per the 2020 census, the population of the village was 50,248. It is a south-western suburb of Chicago located between I-88 and I-55. History Downers Grove was founded in 1832 by Pierce Downer, a farmer who traveled to Illinois from Rutland, New York, but was originally from Vermont. Downers Grove was named for a lush grove of old-growth bur oak trees surrounding the village, which stood out from the local savanna landscape. Its other early settlers included the Blodgett, Curtiss, Blanchard, Stanley, Lyman, and Carpenter families. The original settlers were mostly migrants from the Northeastern United States and Northern Europe. In 1839, Reverend Orange Lyman, a presbyterian minister, and his wife Maria Dewey Lyman arrived, and built what is believed to be the first home in Downers Grove. The first schoolhouse was ...

Public Service Announcements
A public service announcement (PSA) is a message in the public interest disseminated by the media without charge to raise public awareness and change behavior. Oftentimes these messages feature unsettling imagery, ideas or behaviors that are designed to startle or even scare the viewer into understanding the consequences of undergoing a particular harmful action or inaction (such as pictures of drug users before and after their addiction or realistic skits of domestic violence situations) as well as the importance of avoiding such choices. In the UK, they are generally called a public information film (PIF); in Hong Kong, they are known as an announcement in the public interest (API). History The earliest public service announcements (in the form of moving pictures) were made before and during the Second World War years in both the UK and the US. In the UK, amateur actor Richard Massingham set up Public Relationship Films Ltd in 1938 as a specialist agency for producing short ...

Radio Stations In Chicago
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minidisc
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, or 80 minutes of digitized audio. Sony announced the MiniDisc in September 1992 and released it in November of that year for sale in Japan and in December in Europe, North America, and other countries. The music format was based on ATRAC audio data compression, Sony's own proprietary compression code. Its successor, Hi-MD, would later introduce the option of linear PCM digital recording to meet audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan and found moderate success in Europe. Although it was designed to succeed the cassette tape, it did not manage to supplant it globally. By March 2011, Sony had sold 22 million MD players, but discontinued further development. Sony ceased manufacturing and sold the last of the players by March 2013. On January 23, 2025, Sony announced they would end the production of recordable MD media ... [...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 eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
