description A method and apparatus are provided for receiving electromagnetic radiation within a frequency band. The receiving is accomplished by intercepting electromagnetic radiation within the frequency band and converting the intercepted electromagnetic radiation into an electrical signal (102). Subsequently, a portion of the electrical signal (102) is digitized (104) into digitized signals (112, 113, 114). Each digitized signal (112, 113, 114) represents the intercepted electromagnetic radiation within a portion of the frequency band. Finally, a composite digitized signal (118) is generated (116) from at least two of the digitized signals (112, 113) 114). Alternatively, the receiving process may be enhanced by intercepting (188) first electromagnetic radiation (192) within a portion of the frequency band and by intercepting (190) second electromagnetic radiation (194) within another portion of the frequency band. Subsequently, the first and the second electromagnetic radiation (192, 194) is combined (196) into a composite electromagnetic radiation waveform (198). The composite electromagnetic radiation waveform (198) is converted into an electrical signal which may be processed (204) into digitized signals (206, 208) which form a composite digitized signal (118).
