Spectral Analysis下載 PDF選擇的小節所選的小節與子小節完整手冊已更新2025-07-30閱讀時間為 2 分鐘LabVIEWAPI 參考LabVIEW G Use the Spectral Analysis VIs to perform array-based analysis on a spectrum. The VIs on this palette can return signal processing error codes. Auto Power Spectrum VIComputes the single-sided, scaled, auto power spectrum of a time-domain signal.Power Spectrum VIComputes 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. Cross Power Spectrum VIComputes the single-sided, scaled, cross power spectrum of two real-time signals.Unevenly Sampled Signal Spectrum VICalculates the power spectrum of a signal that is unevenly spaced in time.Amplitude and Phase Spectrum VIComputes the single-sided, scaled amplitude spectrum of a real-valued time-domain signal and returns the amplitude spectrum as magnitude and phase.Spectrum Unit Conversion VIConverts either the power, amplitude, or gain (amplitude ratio) spectrum to alternate formats including Log (decibel and dbm) and spectral density.STFT Spectrograms VIComputes the signal energy distribution in the joint time-frequency domain, using the short-time Fourier transform (STFT) algorithm.WVD Spectrogram VIComputes the energy distribution of the input signal in the joint time-frequency domain using the Wigner-Ville distribution (WVD) algorithm.Cross Power VIComputes 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.Power & Frequency Estimate VIComputes the estimated power and frequency around the peak frequency in the power spectrum of a time-domain signal.Buneman Frequency Estimator VIEstimates the frequency of a given sine wave of unknown frequency using the Buneman formula.Parent topic: Signal Processing
