Research and Design of Virtual FIR Digital Filter Based on LabVIEW

摘要

Digital filter technology is quite important in the signal processing field. This paper realizes digital filter designing by way of the virtual instrument technology, and this paper introduces the filter plat front panel and program frame diagram designing based on the FIR filter algorithm through the LabVIEW platform. Through the simulation, the virtual digital filter validates the designing accuracy. The digital filter achieves the ideal effect in filtering, which can be widely applied into the signal processing field, such as digital de-nosing, and experimental study, etc. Digital filter panel designing has broad application prospect and research value.
