I'm with you there Mark. They don't explain how to calculate the parallel value of the two bias resistors, why that is relevant, and of course linking all that together via Thevenin. Then they use the beta transform to move that parallel combination to the emitter side, again without an iota of explanation. They leave re out of it, which is probably reasonable because at 4mA is it just 6.5 ohms.
And then they have the effrontery to call the site "Learning about Electronics"; when it actually teaches precisely nothing at all.
Meaning no disrespect sir but did you actually review the site? After reading these comments I checked the site out. If you go to the home page and click articles it starts with what is a resistor, how are resistor constructed, what are resister used for.... Then capacitors and coils etc. If you took the Radio Engineers Handbook as your textbook and flipped to page 1000 to start reading you would be were this thread is. No they can\'t reteach the basic theory on every page. They start with we know nothing and build on the subject. It would be like taking calculus without taking basic math or algebra when you jump to the end of the book to start.Don't hit me! I was an electronics instructor and had students come in day one wanting to ask about the third weeks material. They had read an article in Popular Electronics and thought they could bypass the basics. I'm just saying maybe you should start on page one of the book before passing judgement?
