Sub-Nyquist Sampling Algorithm Implementation on Flex Rio The project is part of the Sub-Nyquist sampling and reconstruction card. Our goal was to implement DSP unit on FlexRio FPGA card under NI LabView environment, it includes integration to the full system (NI Chassis with 3 FlexRio FPGA cards).
