QWTB — Software tool box for sampling measurements

A new software toolbox QWTB is presented. It aims for aggregation of high-quality algorithms required for data processing of sampled measurements. Algorithms include frequency, amplitude and phase estimators, stability quantifiers, flicker calculator etc. The toolbox unifies and simplifies user interface of algorithms and an example for every algorithm is included to help understanding. The toolbox is open-source and an addition of new algorithms is very easy thus the toolbox can be extended by anyone. The software is written in MATLAB® code and is also executable in GNU Octave. Graphical user interface and link to LabVIEW is also provided.
