Qucs: A circuit simulator
Launch Qucs: Applications --> Electronics --> Qucs.
Qucs presents a window subdivided in two sections. The main section is an area that houses Schematic (design window) where you place your electrical components, and Data Display (simulation window), where you visualize the analytical results. The other section, on the left, has three visualizations mode: Components, Contents and Projects. In the Components view, you can navigate between various categories, selecting the drop-down list at the top of its window. If you need a DC Voltage source, source; a Resistor, Capacitor or Inductance, lumped components; a diode or a transistor non-linear components. So if you work in the G-Hz range or in the u-wave sector, select Trasmission-Lines.
Drag and drop the components in the Schematic area. Here you can Rotate the elements and the associated labels, using the context-menu (right clicking on the element) or the buttons at top window, for better placing.
To connect the elements, click on the Wire button, which transforms the mouse punctator in two perpendicular lines. Position and click the mouse on the red circle terminal, and complete the connection: a dashed line previews the connection. To exit from wire-mode de-select the wire button or activate select mode, clicking on the Select button.
To begin, create a schematic, like this, o download one from this site:
