linNet

linNet is an application to compute the transfer function of linear,
electronic circuits. The computation is done symbolically, not
numerically, and the result is a formula rather than a number or a series
of such. The found formula is the Laplace transform of the dependencies of
the voltages and currents in the circuit on the input voltages and
currents.

A linear electronic circuit is a combination of the supported basic
devices; these are resistor, conductance, capacitor, inductivity,
operational amplifier, voltage source (constant or controlled by another
voltage or current), current source (constant or controlled by voltage or
another current) or a current probe (i.e. a wire). The circuit is
described by a netlist.

The computed formulas can be used for further investigation of the circuit
or for publications or didactic purpose. An interface to GNU Octave opens
up a bunch of simple to use numeric analyses and plots.
