Dataplore - Range of functions

  • Histogram plots and 2D or 3D delay and phase plots of signals
  • Evaluation of signal statistics (mean, standard deviation, skewness, kurtosis, modes, median, linear regression coefficients etc.), central moments and various statistical tests
  • Signal manipulation: subsampling, DC removal, linear compensation
  • Generation of surrogate data and noise signals: fractal, Gaussian, Poisson etc.
  • Arithmetic operations and mathematical functions: sin, cos, exp, sinh, log, asin, erf etc.
  • Analytical operations: time derivative, integration, autocorrelation, cross correlation, instantaneous analytical phase, Hilbert transformation
  • Fourier transformation: amplitude, power and phase spectrum with optional windowing, cross spectrum, chirp-z transformation, cepstrum, coherence etc.
  • Linear filters: FIR filters, IIR filters, frequency domain filters
  • Wavelet transforms: decomposition and reconstruction with orthogonal and biorthogonal wavelets, approximation and detail calculation
  • Methods of nonlinear dynamics: recurrence plots, peak-to-peak intervals, correlation integral and dimension, global and local Lyapunov exponents, global and local transinformation of two time series etc.
  • Advanced noise reduction methods: wavelet shrinking and nonlinear noise reduction techniques
  • All standard options, like file I/O, printing capabilities etc.
  • Support of various file formats: Dataplore binary and ASCII formats, MegaWave, WAVE audio files, ASCII raw data
  • Signal handling: mouse-supported clipping, editing of signal properties
