Maple offers many tools for analyzing and manipulating signals and images.



Maple offers many tools for analyzing and manipulating signals and images.

  • Use FFTs, wavelets, Lomb-Scargle analyses for irregularly sampled data and more
  • Perform upsampling and downsampling, and use interpolation to fill in gaps
  • Generate periodograms, spectrograms, phase and magnitude plots and more
  • Import and export many types of data, including Excel, text, audio and images
  • Take advantage of symbolic math that helps you understand concepts such as convolution
  • Employ units-aware numeric solvers that help you solve iterative problems, such as those that arise in antenna design
  • Explore a large collection of examples and applications
  • Do and document your analyses in a single interface, and deploy to the desktop and web
  • Apply signal processing techniques to digital twins developed in MapleSim

Signal Processing Features

Maple’s signal processing tools include the following:

  • Signal Preprocessing & Generation: Smoothing, denoising, detrending, outlier removal, resampling, waveform generation, interpolation (regular and irregular grids) etc.
  • Filters: Digital (IIR/FIR), analog filters
  • Transforms: FFT (1-D & 2-D), DFT, DCT, wavelets, real & complex cepstrum
  • Spectral Analysis: Periodogram (1-D and images), spectrogram, Lomb-Scargle
  • Signal Analysis: Convolution, cross-correlation, autocorrelation, peak finding, signal statistics
  • Miscellaneous: Bode/Nyquist/Root-Locus, curve fitting, multivariable regression, symbolic math, transfer functions, state space, DEs, optimization, numeric and symbolic solvers
  • Import/Export: Text, Excel, audio, databases, images, binary files

In addition to the Signal Processing package, Maple provides many other packages useful in signal processing applications, including:
