Description

Benefit

Easy-to-use windows interface

• Easy to use dialog boxes
• Toolbar and menu driven dialog boxes for spectral techniques, signal processing and graphical and numeric outputs.
• Full 32-bit performance

• No programming of procedures, algorithms or graphing!
• Perform your work 10X faster and enable you to perform 10X more analysis routines to get a complete picture
• Enables you to focus on your analysis not on learning the program.

Spectral Analysis - FFT

• FFT for Fast Fourier Transform
• Identify frequency and power of a signal
• More than just standard Fourier Transform - 5 additional FFT methods including FFT with taper windows, FFT tapering window comparison, FFT of segmented data, Multitaper FFT and Unevenly sample FFT.
• 30 tapering windows available to solve FFT leakage concerns
• Zero padding available

• FFT is a popular technique
• Accurate technology when you have large data sets
• Can get both frequency and power accurately

• Handles non-stationary data meaning can find frequency of signal based on the when it occurred rather than computing the frequency for the entire period of the signal
• Can see wavelets in 3D or contours
• Wavelet spectra can be generated with up to 100 linear or logarithmic frequencies
• Adjustable mother wavelets available: Morlet (most common), Paul and Gaussian Derivative

• Simultaneously find time and frequency localization components of non-stationary periodic signals.

Spectral Analysis - AR

• AR stands for AutoRegressive
• Includes AR, MA (Moving Average) and ARMA
• 14 algorithms available

• Great technique for small data sets

Spectral Analysis - Eigen Analysis

• Eigen Analysis partitions by signal strength using adaptive non-parametric basis functions.
• Signal components can be separated by differences in power.
• Eigen Analysis also known as Eigendecomposition, singular spectrum analysis, principal component analysis and eigenfiltering.
• Also available in certain parametric procedures

• Excellent signal-noise separation
• Excellent component isolation
• Can easily select signal and noise sub-space graphically

Spectral Analysis - Prony

• Fits damped sine and damped exponential that occur in multivariate exponential decays

• Fits damped signals that are normally difficult to fit

Non-linear parametric modeling

• Optimize your spectral analysis fits either as an independent procedure or as an adjunct to your spectral procedure
• If used as an adjunct, you perform a spectral technique and then you constrain the frequency to optimize the spectral fit

• Get the most accurate fits possible

Production Facility

• Automate your analysis and reporting with the production facility that uses your preset options
• Import: Import multiple data sets from Excel 95/97 with up to 255 worksheets and multiple rows per worksheet or DLL interface to hardware
• Export numerical summaries and/or graphs to MS Word RTF documents
• Export resulting analysis to Excel 95/97 to one or up to 255 worksheets

• Perform unattended analysis and generate professional reports
• Save valuable research time by performing repetitive analysis routines without manual intervention

Smoothing and denoising

• Perform smoothing and denoising with advanced Fourier, eigen and wavelet methods or use time-series smoothing such as Savitzky-Golay, spline and Loess.

• Eliminate high frequency noise from the signal

Filtering and Reconstruction

• Isolate components and detect signals and reconstruct with Fourier, eigen and wavelet techniques.

• Find and use only the signal components that you are interested in

Graphical Review

• Spectral peaks are identified graphically
• Flexible display of spectra peaks, frequencies and magnitudes
• 3D animation
• View residuals, plot roots and plot selection criteria

• Instantly see your results
• Can create publication quality graphs

Critical Limits

• Ascertain the significance of the spectral components to disprove the null hypothesis
• Critical limits: 50%, 90%, 95%, 99%, 99.9%
• Peak-type critical limits generated using Monte Carlo

• Truly determine the significance of a spectral peak

Data Input

• Import data from a variety of file formats which include ASCII, Excel, WAV, Lotus, Quattro Pro, SigmaPlot, SYSTAT, dBase, DIF, and SPSS.
• Can filter down as many as 65.4 million data points from a file with decimation import option. Import preview option enables you to immediately visualize the fit to your data.

• Provides flexibility to work with a variety of file formats.
• You can handle large data sets.
• Enables you to immediately see what your data looks like

Extensive output options

• AutoSignal offers you with a wide variety of output options.
• Automatically generate reports with numeric summaries and graphics directly to MS Word RTF with just a click of a button
• Create publication-quality graphs or export the data to your favorite spreadsheet including Lotus, Excel, Quattro Pro, SigmaPlot spreadsheets
• You can also export image files as bitmaps, metafiles, enhanced metafiles and device-independent maps

• You have the flexibility of analyzing your data further the way they want to, or you can incorporate publication quality graphs into reports.
• Create reports with built-in automation
