  • Sideband — The power of an AM signal plotted against frequency. Key: fc is the carrier frequency, fm is the maximum modulation frequency In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, containing …   Wikipedia

  • Upper Side Band — Seitenbänder nennt man die Frequenzbänder, die durch die Modulation einer Trägerfrequenz mit einem Nutzsignal erzeugt werden. Hierbei entstehen im Regelfall Summen und Differenzfrequenzen der beiden Signalfrequenzbereiche zueinander. Die durch… …   Deutsch Wikipedia

  • sideband — A range of frequencies occupied by the spectral components resulting from the modulation of a carrier wave by a signal. The frequency of the upper sideband is the sum of the carrier frequency and the audio frequencies used to modulate the carrier …   Aviation dictionary

  • Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… …   Wikipedia

  • Single-sideband suppressed-carrier transmission — Single sideband suppressed carrier (SSB SC) is a telecommunication technique, which belongs to the Amplitude modulation class.The information represented by the modulating signal is contained in both the upper and the lower sidebands. Since each… …   Wikipedia

  • Independent sideband — (ISB) is an AM single sideband mode which is used with some AM radio transmissions. Normally each sideband carries identical information, but ISB modulates two different input signals mdash; one on the upper sideband, the other on the lower… …   Wikipedia

  • Compatible sideband transmission — Compatible sideband transmission: Independent sideband transmission in which the carrier is deliberately reinserted at a lower level after its normal suppression to permit reception by conventional AM receivers. Compatible sideband transmission… …   Wikipedia

  • Single-sideband modulation — Bande latérale unique Pour les articles homonymes, voir BLU et SSB. La bande latérale unique ou BLU (en anglais : SSB – Single sideband modulation) est un mode de modulation pour la radio qui consiste en une modulation d amplitude dans… …   Wikipédia en Français
