Virtual Filter Design Based on LabVIEW Development Platform

The virtual filter system based on the concept of modularization is designed and implemented on the LabVIEW development platform in this paper. The design includes signal generator, window function and filter processer. The signal generator generated candidate waveform signals added by Gaussian white noise and delivered to the window function and filter processer to process and analysis the signal. It filters out the noise by designing the filter reasonably. The test shows that the virtual filter can meet the application requirements, and it has strong practicability.
