double-sideband transmission

double-sideband transmission

[¦dəb·əl ¦sīd‚band tranz′mish·ən]
(communications)
The transmission of a modulated carrier wave accompanied by both of the sidebands resulting from modulation; the upper sideband corresponds to the sum of the carrier and modulation frequencies, whereas the lower sideband corresponds to the difference between the carrier and modulation frequencies.

(Current standards choose the band center to be between 1,700 and 1,800 Hz.) Thus, with a double-sideband transmission scheme, the maximum signaling rate is about 2,400 samples per second.
