the energy of a discrete-time signal x(t) is defined as
Relationship to energy in physics
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.
"Energy" received acclaim from music critics with many calling it the best song of the album. Ryan Dombal of Pitchfork gave the song a positive review and named it "Best New Track", stating "The song isn't aimed to any rappers or pop stars, not Kendrick Lamar, Big Sean or Tyga, but the song lines are dangerous."
The video of "Energy" was released on Apple Music and users with iTunes and registered Apple Music account can watch this video.
"Energy" is a song performed by American singer Melissa Manchester, from her 1985 album Mathematics.
The song was arranged by veteran songwriter Greg Mathieson and was released as the second single from the album, following the underperformance of the lead single "Mathematics", MCA hoped to reverse the album's fortune by releasing this Hi-NRG track with an aim for the club market.
Melissa Manchester filmed a videoclip to promote the song, which sees the singer and her band in a sort of industrial-setting stage performing the song.
The single was released on 7" and 12" formats featuring remixes, but it failed to chart either on the Billboard Hot 100 or the dance charts, and failed to chart elsewhere. The b-side to the single was a non-album song, called "So Full Of Yourself", which was co-written by Manchester and Tom Snow and used as the b-side to all 3 singles off the album.

The Salt River (O'odham [Pima]: Onk Akimel, Yavapai: ʼHakanyacha or Hakathi:) is a stream in the U.S. state of Arizona. It is the largest tributary of the Gila River. The river is about 200 miles (320km) long. Its drainage basin is about 13,700 square miles (35,000km2) large. The longest of the Salt River's many tributaries is the 195-mile (314km) Verde River. The Salt's headwaters tributaries, the Black River and East Fork, increase the river's total length to about 300 miles (480km).
