Signal Analysis Express VIs (PDA Module, Touch Panel Module)
Owning Palette: Express VIs and Functions
Use the Signal Analysis Express VIs to perform waveform measurements, waveform generation, and signal processing.
| Palette Object | Description |
|---|---|
| Convolution and Correlation | Performs convolution, deconvolution, or correlation on the input signals. |
| Create Histogram | Computes a histogram for Signal. |
| Curve Fitting | Computes the coefficients that best represent the input data based on the chosen model type. |
| Distortion Measurements | Performs distortion measurements on a signal, such as tone analysis, total harmonic distortion (THD), and signal in noise and distortion (SINAD). |
| Dual Channel Spectral Measurement | Measures the frequency response of the input signals and the coherence based on the current and previous input signals. This Express VI returns results such as Magnitude, Phase, Coherence, Real, and Imaginary. |
| Filter | Processes signals through filters and windows. |
| Mask and Limit Testing | Performs limit testing on Signals. The Express VI compares Signals with upper and lower limits that you set. |
| Simulate Signal | Simulates a sine wave, square wave, triangle wave, sawtooth wave, or noise signal. |
| Spectral Measurements | Performs FFT-based spectral measurements, such as the averaged magnitude spectrum, power spectrum, and phase spectrum on a signal. |
| Statistics | Returns the selected parameter of the first signal in a waveform. |
| Tone Measurements | Finds the single tone with the highest amplitude or searches a specified frequency range to find the single tone with the highest amplitude. You also can find the frequency and phase for a single tone. |
