In this paper, a sub-Nyquist sampling system for multiband signals is presented, which can perform accurate spectrum sensing and reconstruction. The system is based on PXI bus and virtual instrument technology, which make the proposed system able to be adjusted flexibly for different input signals. Compressive sensing (CS) theory and modulated wideband converter (MWC) are adopted in the system. The...
The overall design use two-stage distributed control module to test the performance indicators of the potentiometer in the servo control system, in order to determine whether they meet the control requirements. The host PC use graphical design based on virtual instrument Labwindows/CVI which is easy human-computer interaction. Its function includes sending test commands, data analysis and processing,...
