linNet
The Software for symbolic Analysis of linear Electronic Circuits
...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. ... -

Precision_trimmer
Precision resistance value trim circuit using standard parts.
By using standard precision resistors in parallel and series with standard 1, 2, 5 multiple potentiometers, a precision, narrow range resistance trimmer can be created. Fixed resistors are more stable than potentiometers and the circuit reduces the effects of the potentiometer while also determining a precise range. For convenience, a Python script is used to assist in part selection. -
