Feedback

Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself. The notion of cause-and-effect has to be handled carefully when applied to feedback systems:

History

Self-regulating mechanisms have existed since antiquity, and the idea of feedback had started to enter economic theory in Britain by the eighteenth century, but it wasn't at that time recognized as a universal abstraction and so didn't have a name.

The verb phrase "to feed back", in the sense of returning to an earlier position in a mechanical process, was in use in the US by the 1860s, and in 1909, Nobel laureate Karl Ferdinand Braun used the term "feed-back" as a noun to refer to (undesired) coupling between components of an electronic circuit.

By the end of 1912, researchers using early electronic amplifiers (audions) had discovered that deliberately coupling part of the output signal back to the input circuit would boost the amplification (through regeneration), but would also cause the audion to howl or sing. This action of feeding back of the signal from output to input gave rise to the use of the term "feedback" as a distinct word by 1920.

The Life of Pablo

The Life of Pablo is the seventh studio album by American recording artist Kanye West. It was released by GOOD Music and Def Jam Recordings on February 14, 2016. The album was initially available exclusively through the streaming service Tidal, following a lengthy series of delays in its recording and finalization. Recording of the album dated back to recording sessions for West's fifth album, My Beautiful Dark Twisted Fantasy (2010), and took place in various locations.

Background

West began working on his seventh solo album in November 2013. The album was originally titled So Help Me God and slated for a 2014 release. This version of the album, which never materialized, included several tracks which were released such as "God Level" (released as part of an Adidas World Cup promo), "Tell Your Friends" (later given to The Weeknd), "3500" (given to Travis Scott), "All Day" and "Only One". In February 2015, the only tracks from this version appearing to make the final cut for The Life of Pablo were "Famous" (formerly titled "Nina Chop") and "Wolves", which West performed on Saturday Night Live's 40th anniversary episode, with American recording artists Sia and Vic Mensa.
