12 Qucs is an integrated circuit simulator which means you will be able to
13 setup a circuit with a graphical user interface (GUI) and simulate the
14 large-signal, small-signal and noise behaviour of the circuit. After
15 that simulation has finished you will be able to present the simulation
16 results on a presentation page or window.
17
18 The software aims to support all kinds of circuit simulation types,
19 e.g. DC, AC, S-parameter, harmonic balance analysis, noise analysis,
20 etc.

22 QucsActiveFilter is the active filter synthesis tool used by Qucs. By
23 use of an input dialog the user can create a filter which is then
24 copied into the system-wide clipboard. In Qucs the user opens an empty
25 schematic and presses CTRL-V (paste from clipboard). The filter
26 schematic is now inserted and can be simulated.
27
28 Available filter types are: Butterworth, Bessel, Chebyshev, Cauer.
29
30 Available topologies are: Sallen-Key, Multifeedback and Cauer.
