Abstract

An apparatus for frequency content separating an input signal is disclosed. The apparatus comprises a plurality of frequency splitting stages, each stage including one or more up-converter and down-converter pairs. An up-converter and down-converter pair serves (i) to receive a complex input signal representing an input bandwidth and (ii) to output a first complex output signal representing an upper portion of the input bandwidth and a second complex output signal representing a lower portion of the input bandwidth. The upper portion and the lower portion being contiguous and together representing the input bandwidth portion.
