Another hopeless text: spot the errors...
 

Hi guys,

Still reeling from the screw-up Chris Bowick made of his explanation
of FET biasing, I've come across this little gem which purports to
show the design considerations for a FET amplifier stage which takes
into account the spread of parameters one encounters with FETs:

"Solved problems"? I don't think so. I'm up to six glaring errors
already, but I'm sure there are more yet to be found. How many can
*you* spot?

I've never come across his book but if it was me I'd have thrown the bloody
thing away years ago.

Well, it does say, "If you are from some other university then confirm
with your professors whether these formulae/methods are valid for your
university."

Hehe! I don't blame you, John. But I should perhaps have made it
clearer that the link I posted has nothing to do with Bowick. It's
coursework by some lecturer at Bombay University.

So are the laws of physics different elsewhere?

I first read this as:
If you are from some other universe then confirm
with your professors whether these formulae/methods
are valid for your universe.

Indeed! I don't think western designers have much to fear (job
competition-wise) from graduates of Bombay University. :-)

It appears so. Everywhere outside of Bombay, I guess.

That was just in the state of Tennessee (or maybe Kentucky). Don't
think it actually passed.

But it illustrates the wisdom of having legislators make decisions
about science.

They (the politicians) were relying on that vast storehouse of
scientific information, the
Bible, for their instruction.

I missed that part. Guess it would be in the Book of Numbers.

On the other hand, I do not know of anyone who searches for religious
instruction in a calculus textbook.
