Signal package

From Octave
Jump to: navigation, search

The signal package is part of the Octave Forge project and provides signal processing algorithms for use with Octave. The functions provided by the signal package include creation of waveforms, FIR and IIR filter design, spectral analysis, Fourier and other transforms, window functions, and resampling and rate changing.
