Owning Palette: Signal Processing VIs
Requires: Full Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Spectral Analysis VIs to perform array-based analysis on a spectrum.
The VIs on this palette can return signal processing error codes.
|Amplitude and Phase Spectrum||Computes the single-sided, scaled amplitude spectrum of a real-valued time-domain signal and returns the amplitude spectrum as magnitude and phase.|
|Auto Power Spectrum||Computes the single-sided, scaled, auto power spectrum of a time-domain signal.|
|Buneman Frequency Estimator||Estimates the frequency of a given sine wave of unknown frequency using the Buneman formula.|
|Cross Power||Computes the cross power spectrum, Sxy, of the input signals X and Y. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.|
|Cross Power Spectrum||Computes the single-sided, scaled, cross power spectrum of two real-time signals.|
|Power & Frequency Estimate||Computes the estimated power and frequency around the peak frequency in the power spectrum of a time-domain signal.|
|Power Spectrum||Computes the Power Spectrum, Sxx, of the input sequence X. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.
|Spectrum Unit Conversion||Converts either the power, amplitude, or gain (amplitude ratio) spectrum to alternate formats including Log (decibel and dbm) and spectral density.|
|STFT Spectrograms||Computes the signal energy distribution in the joint time-frequency domain, using the short-time Fourier transform (STFT) algorithm.|
|Unevenly Sampled Signal Spectrum||Calculates the power spectrum of a signal that is unevenly spaced in time.|
|WVD Spectrogram||Computes the energy distribution of the input signal in the joint time-frequency domain using the Wigner-Ville distribution (WVD) algorithm.|
