The sideband used by a low-intermediate-frequency transmitter for transmitting signals on a channel is selectable. In some embodiments of the invention, the sideband used for transmitting signals is selected based on the location of the channel within a band of channels. In such embodiments, the lower sideband may be selected for transmitting signals if the channel is the lowest-frequency channel in the band, and the upper sideband may be selected for transmitting signals if the channel is the highest-frequency channel in the band. Such sideband selection results in image power falling within the band, which can be helpful in complying with out-of-band power limitations.
