linsmith — Smith charting program, designed for educational use.


linsmith [-d opts]


This manual page briefly documents linsmith. It was written for the Debian GNU/Linux distribution because the original program does not have a manual page. A more complete manual is included (in PDF form) with the installation.

linSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

It's main features are:
* Definition of multiple load impedances (at different frequencies)
* Addition of discrete (L, C, parallel and series LC, and transformer) and line components (open and closed stubs, line segments)
* Connection in series and parallel
* Easy experimentation with values using scrollbars
* A 'virtual' component switches from impedance to admittance to help explaining (or understanding) parallel components
* The chart works in real impedances (not normalized ones)
* Direct view of the result on the screen
* Ability to generate publication quality Postscript output
* A 'log' file with textual results at each intermediate step
* Load and circuit configuration is stored separately, permitting several solutions without re-defining the other


This program is mainly designed for graphical use, and therefore does not have many options. A summary of options is included below.
