ABSTRACT:
A channelizer for processing a wideband signal to extract a plurality of narrowband signals is disclosed. The channelizer is capable of processing a received wideband signal to extract a plurality of regularly spaced narrowband signals therefrom. The wideband signal is processed in such a manner that the extracted narrowband signals have a sampling frequency that is not limited to an integer multiple of the channel spacing and is valid for any combination of downsampling factors and number of channels.
