National Instruments 374318A-01 用户手册

The Measurement Studio Analysis .NET class library is in the 

NationalInstruments.Analysis

 namespace. The Analysis class 

library includes a set of classes that provides various digital signal 
processing, signal filtering, signal generation, peak detection, and other 
general mathematical functionality. Use this library to analyze acquired 
data or to generate data.

The Analysis class library includes the following functionality:

•

Sawtooth, sine, square, triangle, and basic function wave generators.

•

Bessel, Chebyshev, Inverse Chebyshev, Windowed, Kaiser, and 
Elliptic Low, High, Bandpass, and Bandstop filters

•

Signal processing functions such as convolution, deconvolution, 
correlation, decimation, integration, and differentiation

•

FFT, Inverse FFT, Real FFT, Fast Hartley, Inverse Fast Hartley, Fast 
Hilbert, Inverse Fast Hilbert, DST, Inverse DST, DCT, and Inverse 
DCT transformations

•

Linear algebra functions such as determinant, check positive 
definiteness, calculate dot product, and other various matrix functions

•

Scaled and unscaled windowing classes

•

Common statistical functions such as mean, median, mode, and 
variance

•

Exponential, linear, and polynomial curve fitting functions

•

Signal generation functions
