Filter (TV series)

Filter is an American television series on the G4 cable television channel which follows a countdown format. It was canceled in December 2005, resurrected in a re-formatted form, and then once again was canceled in August 2006. It was airing as an interstitial program during commercial breaks prior to May 2012. The show allows registers users (or viewers) to vote in Top Ten lists.

History

Filter was one of the 13 original series to debut with G4. The focus of the show was video games, and each episode covered a different genre, such as sports or role-playing video games. Each week a new theme was chosen and viewers chose the top ten to be featured on the show. The top two games would be put in a Filter Face-off, where the winner was revealed. Shows included the top ten Final Fantasy games, worst games of all time, and all-time top-ten platformers.

After the purchase of TechTV, Filter was revamped to include more pop culture lists such as theatrical and DVD movie releases, music concerts, and consumer technology. The segment "Tech Toss-up" was added to cover new gadgets such as cellphones and MP3 players. A segment called "Net to Know" showcased correspondent John Walsh's top three websites of the week.

Filter (band)

Filter is an American industrial rock group formed in 1993 in Cleveland by singer Richard Patrick and guitarist/programmer Brian Liesegang. The band was formed after Patrick desired to start his own band after leaving Nine Inch Nails as their touring guitarist. Their debut album, Short Bus, was released in 1995, and ended up going platinum, selling over one million copies, largely due to the success of the band's single "Hey Man Nice Shot." After the album, the band would go through the first of many line-up changes, leaving Patrick as the only consistent member across all music releases.

Patrick released the band's follow up album, Title of Record, which also went platinum, off the success of the song "Take a Picture", in 1999, and a third album, The Amalgamut, in 2002, before checking into rehab after years of heavy alcohol and drug abuse. The band went into hiatus while Patrick went to rehab, and then formed a new band, Army of Anyone, which released one self-title album. Filter reformed in 2008 to release Anthems for the Damned, and then The Trouble with Angels in 2010, with Patrick and a revolving door of other musicians. Filter's sixth and most recent studio album, The Sun Comes Out Tonight, was released in 2013. A seventh studio album is scheduled for release in 2016.

Electronic filter

Electronic filters are circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be:

The most common types of electronic filters are linear filters, regardless of other aspects of their design. See the article on linear filters for details on their design and analysis.

History

The oldest forms of electronic filters are passive analog linear filters, constructed using only resistors and capacitors or resistors and inductors. These are known as RC and RL single-pole filters respectively. More complex multipole LC filters have also existed for many years, and their operation is well understood.

Hybrid filters are also possible, typically involving a combination of analog amplifiers with mechanical resonators or delay lines. Other devices such as CCD delay lines have also been used as discrete-time filters. With the availability of digital signal processing, active digital filters have become common.

Fresh water

Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs. The term "sweet water" (from Spanish "agua dulce") has been used to describe fresh water in contrast to salt water. The term fresh water does not have the same meaning as potable water. Much surface fresh water and some ground water are unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants.

Systems

Scientifically, fresh water habitats are divided into lentic systems, which are the stillwaters including ponds, lakes, swamps and mires; lotic systems, which are running water; and groundwater which flows in rocks and aquifers. There is, in addition, a zone which bridges between groundwater and lotic systems, which is the hyporheic zone, which underlies many larger rivers and can contain substantially more water than is seen in the open channel. It may also be in direct contact with the underlying underground water. The majority of fresh water is in icecaps.

Freshwater (opera)

Freshwater is a two-act chamber opera composed by Andy Vores, based on the 1929 comic play by Virginia Woolf. Vores received assistance in creating the opera from Quentin Bell, Woolf's nephew and executor, who provided a rarely seen earlier version of the text that served as the inspiration for several passages of the libretto.

Freshwater was commissioned by the Boston University Opera Institute and had its world premiere on December 2, 1994 at the Huntington Theatre in Boston.
