Abstract
The FFT is an important core to which we couple an M-path partitioned filter and commutator to build high performance spectrum analyzers and channelized transmitters and receivers. With slight modifications of the system the channelizer and spectrum analyzer can perform secondary processing tasks such as arbitrary sample rate changes. Output sample rates can be adjusted to be a multiple of channel spacing or a multiple of the channel symbol rate. With minor additional processing the channelizer can also coherently combine signals from adjacent frequency bands to synthesize arbitrary bandwidth super channels from standard prototype channels.
