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
NTSC — This article is about the television system. For the Indonesian government agency, see National Transportation Safety Committee. Television encoding systems by nation; countries using the NTSC system are shown in green. NTSC, named for the… … Wikipedia
Broadcast television systems — There are several broadcast television systems in use in the world today. An analogue television system includes several components: a set of technical parameters for the broadcast signal, a system for encoding color, and possibly a system for… … Wikipedia
Shortwave radio — Shortwave can also refer to a shortwave trough meteorology. A solid state, analog shortwave receiver Shortwave radio refers to the upper MF (medium frequency) and all of the HF (high frequency) portion of the radio spectrum, between… … Wikipedia
