The problem with beginners book is that they thing the
beginner is *Stupid*.
It is a common mistake to confuse ignroance with stupidity.
TO be, 'stupidity' really means the inability to reason. Ignorance means
not knowing soemthing. For example, I am (very) ignorant on medical
matters, but if a docotr says to me that the food passes through here,
it's digested by enzymes here, etc, then I can follow it. Ignoranat, but
not IMHO stupid.
Same with computer repair. There's a big diffence between not being able
to reason at all, and not knowing any electronics.
I want them *simple*, that deal with the real world. I
am using a FW bridge,
what is the parameters again for output voltage. Ahh see page 45. table #2.
It depenmds on the filter circuit :-). Seriously. It;s roughly the peak
votlage fro a capacitor input filter, the mean of the absolute value of
the waveform for a choke input filter. The Radiotron Designers Handbook
is quite good for thigns like this.
But yes, I see what you mean. Hwoever, I'd prefer a book that explaiend
_why_ the voltages are what they are. That way, if you get a cirucit
that's not in the book you know how to woek it out.
