How To Install linsmith on Ubuntu 18.04
Introduction
In this tutorial we learn how to install linsmith on Ubuntu 18.04.
What is linsmith
linsmith is:
A Smith chart is a tool used in electrical engineering that shows how the complex impedance of a transmission line varies along its length, and simplifies the design of impedance matching networks to match the line to its load.
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.
Its 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
