NAME

QucsFilter - A filter synthesis application.

SYNOPSIS

qucsfilter [OPTION] ...

DESCRIPTION

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, etc.

QucsActiveFilter is the active filter synthesis tool used by Qucs. By use of an input dialog the user can create a filter 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 filter schematic is now inserted and can be simulated.

Available filter types are: Butterworth, Bessel, Chebyshev, Cauer.

Available topologies are: Sallen-Key, Multifeedback and Cauer.

AVAILABILITY

The latest version of Qucs can always be obtained from www.sourceforge.net or www.freshmeat.net
