## Analog and digital frequency design
Following figure shows the current openwifi analog and digital frequency design strategy. It combines AD9361's bandwidth, frequency, sampling rate and FPGA's digital down/up converter (ddc_bank_core.bd/duc_bank_core.bd) setting to achieve this example spectrum arrangement.

It combines AD9361's bandwidth, frequency, sampling rate and FPGA's digital down/up converter (ddc_bank_core.bd/duc_bank_core.bd) setting to achieve this example spectrum arrangement. Values in the figure are configurable in the openwifi design.
