1. An apparatus comprising:
a switching stage for use in a channelizer, the switching stage comprising a plurality of switch circuits that are individually assigned to a plurality of sample periods such that an individual switch circuit applies a matrix operator on a plurality of time-division dempultiplexed input subchannels for an individual sample period, wherein the switching stage is configured to:
receive the plurality of time-division demultiplexed input subchannels, input subchannels of the plurality of time-division demultiplexed input subchannels having been frequency demultiplexed from an input prior to time-division demultiplexing;
at each respective one of the plurality of switch circuits, apply the matrix operator to received time-division demultiplexed input subchannel data for the individual sample period to obtain a plurality of switched time-division outputs for the individual sample period; and
output the plurality of switch time-division outputs for the plurality of sample periods.
