Use the Spectral Analysis PtByPt VIs to implement common transforms used in mathematics and signal processing.

The VIs on this palette can return point by point error codes.

Auto Power Spectrum PtByPt VI
Computes the single-sided, scaled, auto power spectrum of a time-domain signal.
Power Spectrum PtByPt VI
Computes the Power Spectrum, Sxx, of the set of input data points specified by sample length.
Amplitude and Phase Spectrum PtByPt VI
Computes the single-sided, scaled amplitude spectrum of a real-valued time-domain signal and returns the amplitude spectrum as magnitude and phase.
Cross Power Spectrum PtByPt VI
Computes the single-sided, scaled, cross power spectrum of two real-time signals.
Cross Power PtByPt VI
Computes the cross power spectrum, Sxy, of the set of input data points specified by sample length.
STFT Spectrogram PtByPt VI
Computes the signal energy distribution in the joint time-frequency domain using the short-time Fourier transform (STFT) algorithm.
WVD Spectrogram PtByPt VI
Computes the signal energy distribution in the joint time-frequency domain using the Wigner-Ville distribution algorithm.
Buneman Frequency Estimator PtByPt VI
Estimates the frequency of a given sine wave of unknown frequency using the Buneman formula.
