Use the Signal Processing VIs to perform signal generation, digital filtering, data windowing, and spectrum analysis.

Waveform Conditioning
Use the Waveform Conditioning VIs to perform digital filtering and windowing.
Signal Generation
Use the Signal Generation VIs to generate one-dimensional arrays with specific waveform patterns. The Signal Generation VIs generate digital patterns and waveforms.
Signal Operation
Use the Signal Operation VIs to manipulate signals and return a signal output.
Windows
Use the Windows VIs to implement smoothing windows and to perform data windowing.
Filters
Use the Filters VIs to implement IIR, FIR, and nonlinear filters.
Spectral Analysis
Use the Spectral Analysis VIs to perform array-based analysis on a spectrum.
Transforms
Use the Transforms VIs to implement common transforms used in signal processing. The LabVIEW FFT-based VIs use different output units and scale factors.
Point By Point
Use the Point By Point VIs to conveniently and efficiently process data a point at a time. Point By Point VIs are included in the LabVIEW Full Development and Professional Development Systems.
Additional Information about the Signal Processing VIs
Waveform Generation
Use the Waveform Generation VIs to generate different types of single and multi-tone signals, function generator signals, and noise signals.
Waveform Measurements
Use the Waveform Measurements VIs to perform common time and frequency domain measurements, such as DC, RMS, Tone Frequency/Amplitude/Phase, Harmonic Distortion, SINAD, and Averaged FFT Measurements.
