Keywords: QUCS QucsStudio SPICE digital filters (search for similar items in EconPapers) Qucs is a circuit simulator with a graphical user. This window is used for displaying schematics, numerical and algebraic model and circuit design data, numerical output data, and signal waveforms and numerial. After that simulation has finished you can view the simulation results on a presentation page or window. After the simulation is complete, you can view the simulation results in a display page or window. An S-parameter Bode plot in Qucs displays the power transfer magnitude (i.e. Another advantage is the schematics editor, enabling easy drawing the filter structure by connecting the blocks of delay, coefficient multiplication and signal summation. Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. And, Qucs contains some Smith charts in the graphing tabs. Click OK and explore the Smith chart by adding markers. Pure digital simulations are also supported using VHDL and/or Verilog. In this example I chose to display S1,1 for S11. In this paper we proposed Qucs/QucsStudio as a simulations tools which is freely available. QUCS, or Quite Universal Circuit Simulator, is a freeware utility that allows you to draw circuit schematics. The design and simulation of digital filters is supported by Matlab® and Simulink, but these tools are very expensive and require training courses. type help loadQucsVariable and help loadQucsDataset). This replaces the schematic entry window labelled (6) in Figure 3. Please use the help function in the Octave command line to learn more about them (i.e. After finishing a simulation successfully Qucs opens a data display window. SIMULATING DIGITAL FILTERS WITH Qucs/QucsStudioĮmil Frenski: SOUTH-WEST UNIVERSITY “NEOFIT RILSKI”, BLAGOEVGRADĮconomics and Management, 2015, vol. There are two Octave functions that load Qucs simulation results from a dataset file: loadQucsVariable() and loadQucsDataset().
