In Christianity, the Holy Spirit or Holy Ghost is one of the three persons of the Holy Trinity who make up the single substance of God; that is, the Spirit is considered to act in concert with and share an essential nature with God the Father and God the Son (Jesus). The Christian theology of the Holy Spirit, or pneumatology, was the last piece of Trinitarian theology to be fully explored and developed. For this reason, there is greater theological diversity among Christian understandings of the Spirit than there is among understandings of the Son (Christology) and of the Father. Within Trinitarian theology, the Holy Spirit is sometimes referred to as the "Third Person" of the Triune God - with the Father being the First Person and the Son the Second Person.
In television, a ghost is an unwanted image on the screen, appearing superimposed on the desired image. In a more specific sense, a ghost is a replica of the desired image appearing fainter and offset in position with respect to the primary image.
Common causes of ghosts (in the more specific sense) are:
Note that ghosts are a problem specific to the video portion of television, largely because it uses AM for transmission. TV is also transmitted on VHF and UHF, which have line-of-sight propagation, and easily reflect off of buildings, mountains, and other objects.
The audio portion uses FM, which has the desirable property that a stronger signal tends to overpower interference from weaker signals due to the capture effect. Even when ghosts are particularly bad in the picture, there may be little audio interference.
Note also that ghosts are specific to analog transmission. Digital television avoids the problems of ghosts altogether, although it has its own artifacts such as block errors. DVB and ISDB use COFDM modulation, which performs well under conditions that produce analog ghosting, while ATSC uses 8VSB, which performs poorly under such conditions.
Co-channel interference is sometimes called ghosting, but it is very different in nature.
Ghosting can also occur in KVM switches, or in VGA video cables, due to poor electromagnetic shielding.
"Ghost" is the ninth track of the Neutral Milk Hotel album In the Aeroplane Over the Sea.
The song's subject matter, like many of the album's songs, deal with themes of death, the afterlife, and eternity. The line "she was born in a bottle rocket, 1929" could be seen as a reference to Anne Frank who was born in 1929.
The end of the song bleeds into the album's tenth, untitled track.
"Ghost" is a song from Phish's 1998 studio release The Story of the Ghost. In the key of A minor, the song is characterized by a slow, funky groove and somewhat surrealist lyrics describing the narrator's relationship with a helpful but elusive spirit ("This was my big secret / How I'd get ahead / I'd never have to worry / I'd call him instead.")
"Ghost" is an historically important part of Phish's repertoire because its basic feel helped to define what many fans perceived as a downshift in energy behind the band's live performances in the late 1990s, a sort of displacement of emphasis from cathartic, high-energy jams to more pensive, sensual, and rhythmically intense improvisations. During this period, a number of the band's songs took on a "Ghost-ish" character in live performance.
"Ghost" was premiered on Phish's 1997 European tour, specifically on June 13, 1997 at Dublin, Ireland. It was last played at the band's final live performance at Coventry, Vermont on August 15, 2004.
