Part 3. SIMULATE ! (to be done)

0. SCOPE OF THIS WORK

The scope of this section is to provide the basic elements to obtain a fully functional simulation model of a tube triode starting from measured data.

We'll follow the "shortest" path to this leaving theory at the minimum to "start working" as soon as possible ;).

Our main steps will deal with how to:

get tube data

choose a model to simulate the data

identify the model's parameter

simulate the model

In all the trade-offs we'll privilegiate the position that will keep the expense in software/hardware/time at the minimum, sacrifing a bit precision, speed, and "good looking interfaces".Besides, We'll count as much as possible on resources found in the WEB.

All that will be referred to a real case, studying a medium mu tube (ECC82).
Because:

It's very common
I think that getting the right parameters is more important when you've to deal with medium and high-mu tubes 'cause of the parameter's very high dispersion
Everything is easyer when you'vr to deal with low consumption ;).
