Hi all!
OK, hopefully this will be a very quick question. Basically, I want to know how to model a vacuum tube (both triode and pentode) in terms of creating a dynamic system model. For example, if were to look at the voltage in an inductor as a function of time, I would employ the relation
[itex]V=L\dfrac{d}{dt}i[/itex]
and then use something like Kirchoff's (current) law to generate a model for the entire circuit--whatever it may be.
So, basically, I guess I have two questions now that I think about it;
First, what sort of relations (like the one above, for example) describe the action of a valve?
Second, what sort of relation (a-la Kirchoff's laws) would apply to the valve as it appears in the circuit? For example, if the amplifying element is an op-amp, the basic (voltage) equation is a constant-times-the-voltage-difference equation--what would I use if my amplifying element was a valve instead?
Many thanks in advance!
