LabVIEW is a system design platform and development environment that uses a graphical programming language. It allows users to visually create programs, called virtual instruments (VIs), by dragging and dropping function nodes onto a block diagram and connecting them. LabVIEW is commonly used for data acquisition, instrumentation control, testing automation, and embedded system design due to its ease of use for data visualization, processing, analysis, parallel programming, and interaction between instruments and communication links. It helps prevent aliasing, a distortion that occurs when a signal is sampled at too low of a sampling rate, making high frequency signals appear as lower frequencies.
