7.9    QProny

The QProny button  in the Simulation tab and Postprocessings->S-Parameters with QProny... command from main menu invoke S-Parameters dialogue with settings for S-Parameters post-processing using QProny module.

Apply Prony method settings refer to the optional QProny software module and can be used together with S-Parameters post-processing. Basically, it reduces the computing time for circuits with sharp features in the frequency domain, such as narrow band pass filters. This is achieved by supplementing the Fourier transform calculations (naturally following time-domain evolution of signals which are physically slow in high-Q cases) with a digital signal processing by Generalised Pencil of Function Method. It allows one to extract the essential features of time signature based on the analysis of time samples obtained at the initial simulation phase. For details, consult a separate QProny manual.

The S-Parameters results can be observed in Results window in QW-Simulator.

Python code

The python code, which can be useful when creating project scripts, generated by S-Parameters dialogue for default parameters for QProny module:

App.ActiveDocument.QW_PostprocessingQProny.Active = True

App.ActiveDocument.QW_PostprocessingQProny.TestEvery = 1000

App.ActiveDocument.QW_PostprocessingQProny.IterationBelow = 100000
