Sideband in a sentence

Vestigial sideband (VSB) VSB modulation A vestigial sideband (in radio communication) is a sideband that has been only partly cut off or suppressed.

Another reason is when the SSB signal is actually a lower sideband, instead of an upper sideband.

His analysis also showed only one sideband was necessary to transmit the audio signal, and Carson patented single-sideband modulation (SSB) on 1 December 1915.

LSB (lower sideband) is generally used below 9 MHz and USB (upper sideband) above 9 MHz.

Since the final RF amplification is now concentrated in a single sideband, the effective power output is greater than in normal AM (the carrier and redundant sideband account for well over half of the power output of an AM transmitter).

The collection of the former frequencies above the carrier frequency is known as the upper sideband, and those below constitute the lower sideband.

The signal components above the carrier frequency constitute the upper sideband (USB), and those below the carrier frequency constitute the lower sideband (LSB).

This places the information terms in quadrature with each other; the Hilbert Transform of information to be transmitted is utilized to cause constructive addition of one sideband and cancellation of the opposite primary sideband.

Transmission in which only one sideband is transmitted is called single-sideband transmission or SSB.

After 1952, licences were required in Canada only for general coverage shortwave receivers with single-sideband capability, and VHF/UHF scanners which could tune to the maritime or land mobile radiotelephone bands.

AGP also uses sideband addressing, meaning that the address and data buses are separated so the entire packet does not need to be read to get addressing information.

A key consequence of the usual double-sideband amplitude modulation (AM) is that the range of frequencies the signal spans (its spectral bandwidth ) is doubled.

Although the bandwidth of an AM signal is narrower than one using frequency modulation (FM), it is twice as wide as single-sideband techniques; it thus may be viewed as spectrally inefficient.

AM stations are still marked on U.S. aviation charts In the early 1930s, single sideband and frequency modulation were invented by amateur radio operators.

An additional audio processing device further improved the sideband structure by selectively applying pre-emphasis to the modulating signals.

An additional function provided by the carrier in standard AM, but which is lost in either single or double-sideband suppressed-carrier transmission, is that it provides an amplitude reference.

Analog QAM suffers from the same problem as Single-sideband modulation : the exact phase of the carrier is required for correct demodulation at the receiver.

Any frequency modulated signal will have an infinite number of sidebands and hence an infinite bandwidth but, in practice, all significant sideband energy (98% or more) is concentrated within the bandwidth defined by Carson's rule.

A single-side band (SSB) or vestigial sideband (VSB) modulation scheme would achieve almost half that bandwidth for the same symbol rate (i.

At all times, the carrier itself remains constant, and of greater power than the total sideband power.
