| 单词 | VSB (Vestigial SideBand) |
| 释义 | VSB (Vestigial SideBand) A technique, used with amplitude modulation (AM), involving the trans- mission of the carrier, one complete sideband and only a portion of the other (vestigial) sideband. (Note: The process of amplitude modulation results in the creation of two sidebands. An upper sideband is above the carrier frequency and a lower sideband is below the carrier frequency.) The vestigial sideband assists in demodulation of the signal. See also 8-VSB, AM, carrier, DSB, frequency, Group II, sideband, and SSB. |
