Abstract
A first mixer (306) shifts a first end (208) of a desired signal frequency bandwidth (206) of a desired signal (202) to an edge (508) of a first filter frequency bandwidth (502) of a first filter (312), wherein the first filter frequency bandwidth (502) is greater than the desired signal frequency bandwidth (206). Signals within a first undesired frequency spectrum (504) are attenuated by the first filter (314). A second mixer (316) shifts a second end (210) of the desired signal frequency bandwidth (206) to an edge (608) of a second filter frequency bandwidth (602) of a second filter (320) to receive the desired signal (202).
