Smart Signal Processing

What the package can do for you

This package provides frequently used functions for signal processing:

  • Computes mean values, variance, standard deviation.
  • Applies windowing (apodization functions) with exponential or Gaussian shapes to an array
  • Applies the Fast Fourier Transform to an array.
  • Calculates the power or magnitude of a complex-valued array.
  • Phase-shifts (rotates in the complex plane) a complex-valued array.

The major API functionalities

  • classes Sigma, BaseLine, WinFunc,FFT, Phase.


  • Multiplication with an exponential:

    WinFunc.expMult(array, decayFactor, false, "0");

  • Compute Fourier Transform:

    FFT.transform(reals, imags);

  • Compute magnitude:

    Phase.magnitude(reals, imags, true)

  • Compute variance in a region:
    Sigma.variance(array, ixstart, ixend)
