LabVIEW Digital Signal Processing Test Platform-Based Design
Abstract: In order to help students understand the digital signal processing course in abstract theory, this paper, based on LabVIEW virtual instrument software, develops a virtual experiment platform for digital signal processing. The experimental platform contains a set of elementary formulas: signal generation, noise signal generation and display, filter, and window function four experiments. Signal generation, mathematics and statistics, digital signal processing and signal display article and other related controls are used in this LabVIEW software platform to design a few basic experiments. Debugging results show that the virtual experiment platform is stable and sound, the man-machine interface is easy to control and preserve, and it also has a strong scalability.
