Just to let people know that I have now made freely available a PDF version
of the book I wrote mumble years ago on Information and Measurement. Can be
obtained from

http://jcgl.orpheusweb.co.uk/Informa...t_PDF_Book.pdf

The explanations use various examples like CD Players, etc, to illustrate
the underlaying methods and science.

Cheers,

Jim

I doubt if I'll understand it but thanks anyway! It's good that a few
people are still prepared to share knowledge for its own sake.

It was written aimed at 'undergrad' levels. So does have 'hard sums'.

However both when I was a student, and a lecturer I realised that books
with more equations then text can be a bar to understanding. Indeed, can
hide that the *author* didn't actually understand something! [1] So I
deliberately included more text than many books on the topic. *And* used a
lot of diagrams and examples. I think/hope that helps people 'get the
idea'. That increases the chance they can sometimes use the maths because
they realise just what it is doing, and how.

In fact, I wrote it as an 'antidote' to books that seem to have been
written to please *lecturers* giving a course. Instead I wanted something
that the *students* might find of use/interest.

So I hope that even if someone has to skip the maths the text may make
various basic points clear.

I think it is the only text on Information that uses a flatiron and kitchen
scales as examples. 8-]

Jim

[1] I found more than one book on Information Theory (and Electromagnetics)
which use a 'mathematical' argument that is actually flawed as a basis for
'explaining' something. I fear each author was copying from earlier books,
assuming it was correct. Which may tell you something about them. :-)

I have, too. I expect that some of it will go over my head but I have a
couple of days coming up with waiting time during the next fortnight, so
I will give it a try then.

I have downloaded it for later perusal. The margins are very wide -
maybe the book was a paperback - so I used Adobe Acrobat to crop the
pages and make another pdf from it, expanding the cropped pages to fill
A4. Now it's easier to read when the display is set to show the whole
page. I also saw that pages 1 & 2 are headed 6 & 7. I could not edit
them because the embedded font is not on my PC, but I removed their
colour so they don't show.

It was. But the printed area was the same as the 1st edition which was
hardback. i.e. bigger than the 'pocketbook' size common for fiction
paperbacks. Printed area per page was much less than A4, as common for such
textbooks. More like what has tended to be called 'Trade' paperback size
for fiction books.

- so I used Adobe Acrobat to crop the pages and make another pdf from
it, expanding the cropped pages to fill A4. Now it's easier to read when
the display is set to show the whole page. I also saw that pages 1 & 2
are headed 6 & 7. I could not edit them because the embedded font is not
on my PC, but I removed their colour so they don't show.


Curious...

The genesis is that I simply combined the set of postscript files I sent to
the printers when the 2nd edition was printed by IoP. I then did tweak a
bit to fix some problems. But didn't really have time to deal with them all
once it seemed readable. The original files were generated many years ago,
so may not be the same as ones which would be generated now.

Here, viewed with Ghostscript, etc, the page numbers seem as I intended.
The printed version used roman numerals for the first pages before the main
text. But I altered this so the page count agreed between what I see on the
page and what page of the document Ghostcript, etc, say you are on. I don't
see here what you report.

I do apologise - I only noticed the page numbering after doing the

cropping, but your original was fine. I repeated the cropping and the
numbering was fine this time, so I don't understand what happened.

One thing I didn't mention was that the Contents pages have random bold
lines. Is this intentional, and if so what is the significance?

Just out of curiosity I downloaded it. He's right about the margins, but
I see no fault in the page numbers, nor odd bold lines.

I was amused by one section:

"[Chapter 19] chose the ill-fated example of DCC (Digital Compact
Cassette). The new version.... uses JPEG and MiniDisc as its examples."

Minidisc. Oh well. JPEG is still going though!

I rather liked MiniDisc. For a while before computer based systems
arrived. Far better than NAB carts, and much cheaper too. I've still got a
stack of domestic Sonys modified to balanced outputs I used to carry
around.
