Qucs is an integrated circuit simulator which means you will be
able to setup a circuit with a graphical user interface (GUI) and
simulate the large-signal, small-signal and noise behaviour of the
circuit. After that simulation has finished you will be able to
present the simulation results on a presentation page or window.
The software aims to support all kinds of circuit simulation types,
e.g. DC, AC, S-parameter, harmonic balance analysis, noise analysis,
QucsAttenuator is the attenuator synthesis tool used by Qucs.
By use of an input dialog the user can create an attenuator which is
then copied into the system-wide clipboard. In Qucs the user
opens an empty schematic and presses CTRL-V (paste from
clipboard). The attenuator schematic is now inserted and can be
Available attenuator topologies types are: Tee, Pi and Bridged-Tee.
