of what I have read so far I'd say that it is NOT for a beginner
It is for a beginner
engineer. As noted in the preface, it evolved from a set of notes for people at Harvard (undergrads, grads, advanced grads, post docs) who suddenly found themselves hampered by their ability to "do electronics".
I wish I'd had it while I was at school (UK school, not a higher education establishment). As it was I had to make do with library books, Wireless World and similar - which couldn't do more than describe a few pieces of a jigsaw.
and is poorly structured as things are not explained in order.
Well, if you could define a single correct order, you might have a point.
Also for a book that claims minimal use of maths it just tells you what a sine wave is mathematically when it could have given a more practical explanation for a book that has minimal maths. I've learnt one thing with books, as soon as the author states that all use of maths has been reduced to a minimum you know that they are talking bollocks and you best get a maths book to go with it.
Engineering requires maths, full stop. It isonly possible to get "so far" with handwaving and pretty pictures; to go beyond that point you need maths. End of story.
