The following table shows the system requirements for the polyphase channelizer. The sampling rate is 2 GSPS. The design supports M=4096 channels with each channel supporting 2G / 4096 = 488.28125 KHz of bandwidth. The filterbank used by the channelizer uses K=36 taps per phase, leading to a total of 4096 x 36 = 147456 taps overall.
