Analysis in Measurement SystemsThousands of engineers and scientists rely on National Instruments software for their test and measurement applications. From the graphical programming interface of NI LabVIEW to the proven ANSI C integrated development environment of NI LabWindowsâ¢/CVI, National Instruments software provides:
Common Analysis AlgorithmsFast Fourier Transform - The fast Fourier transform (FFT) and the power spectrum are powerful tools for analyzing and measuring signals. FFTs are useful for measuring the frequency content of stationary or transient signals. They produce the average frequency content of a signal over the entire time that the signal is acquired. Curve Fitting - Curve fitting is the process of finding a function or model that matches a series of data points and possibly other constraints. The process of curve fitting can be very important for modeling, predicting, and calibrating test and measurement equipment. Sound and Vibration - Sound and vibration analysis can be used in a variety of applications including audio electronics testing, acoustic measurements, environmental noise monitoring, machine condition monitoring, and rotating machinery evaluation.
