Hi guys,

Does exist any DSP book that is moderate on both math and dsp concept?
if so please let me know.

Thanks,
A

I personally have the following reasons for not joining such a group:

1. It is not a usenet standard newsgroup. This means

a. I can't use my own usenet news client and pull down articles from
your group but must instead use Google's web interface.

b. It may not be available across temporal and business boundaries. For
example, your group may disappear in two years should the Google moguls
sell out and the new owners ditch the custom newsgroups.

2. It decentralizes and fragments the focus of people who are
interested in this general area of technology, which I consider well
within the charter of comp.dsp

3. I abhor being advertised to.

Good response, Randy. Hear! Hear!

Hi Amit,

Take a look at DSP first
(http://www.amazon.com/DSP-First-Mult...e=UTF8&s=books)

or Singal Processing First by the same author.

Randy Yates,

If you tell me who will give free hosting for a usenet, I'll look into
starting one. Otherwise, its google groups.

But I didn't realize there was such a cultural and sofware conflict.

DSP-guru, I'm getting the DSP first book by ILL.

I am now reading Tim Westcott's "Applied Control Theory for Embedded
Systems"

I like it very much, and I want to pose some questions about it.

What Tim is describing here is usually known as dynamic controls. Any
other names?

Often it deals with the control of things that move, or change
temperature. Inherent in it is a model of the plant being controlled.

But in popular use, this kind of controls gets lost. I see fuzzy logic
as the antithesis of such. But still, the fuzzy logic people have
claimed some impressive results. They claim to have balanced inverted
pendulums, double jointed inverted, even flexible inverted.

They have no such model, they just tweak.


Likewise, there is the whole body of modern controls, done in the time
domain, without the Laplace or Z-transform. This has now reach the
level of h infinity, an adaptive form.

I don't think Tim deals with this, only with the conventional, or
frequency domain approach.

My concern is that modern controls may not have the kinds of
applicaitons really claimed for it. I learned it in school, but have
questions about how it is really used.

I even question how conventional controls is really used.

I do agree that most of the embedded community knows little of dynamic
controls. Their idea of control lacks the strict real time and tight
plant model.

Comments, views? I'm looking for applications of conventional and
modern controls, and DSP.

So far so good.

Alright, go ahead...

----------------------------
snipped lots of more general questions, provocative statements and
questions about all and everything in general (like "Do you know about
anything where I could use DSP for...?").

Alright. Thank you very much for the invitation. I'm quite happy with
this informative, helpful and (most of the times) even nice community
here. PLEASE stop writing your postings to "come join the group I
created " (sparsely camouflaged as real content) every second day.
Please. In my opinion it is quite ok to have a message about some new
newsgroup or forum or whatsoever, even a second one after some time.
But if not all the people are following you I can't see the point in
spamming that group with the same message (although very creatively
wrapped in a different style every time) again and again. Oh, by the
way: Why not just use THIS group here to discuss the topics in DSP you
are interested in. If you are not sure if this is the right place, why
not have a look at the group's name. Or even ask some people.

But please... (breathing deeply, now far more relaxed...)

Oh, sorry I don't want to short-cut you or offend you (I don't even
know you, so that would be unfair). So if you could tell us what is the
big difference between your group and comp.dsp, or where is the big
advantage to have another group dealing with the very same problems,
please go ahead. If there is no, I can't see the point in splitting the
community and having several places to ask for information, if you
could have one distinctive, easy to find and effective source of help.
Like this newsgroup here.

With best regards

stereo

Frank,

I don't believe starting a new usenet newsgroup would be fruitful. As
I stated before, the topics you mentioned all come within the charter
of comp.dsp, in my opinion.

Secondly, there is no such thing as "free hosting for a usenet."
There is probably some misunderstanding on your part of how
usenet news works. You can find out more by reading

http://en.wikipedia.org/wiki/Usenet

However, in a nutshell, usenet news is distributed to all
newsservers. The usenet standard has defined a mechanism by which
articles are propagated from server to server. So, in theory, if a new
group is defined, all usenet servers will begin carrying the group and
the messages within.

Let me turn the question around and ask you, what is wrong with using
comp.dsp as the forum for your questions? I believe there would be
more than a few people here interested in discussing the sort of
topics you've mentioned.

I'm interested in talking about DSP, here, or in my google group will
will have a bit of a different scope.

I'm not even reading the above two posts from Stereo and Randy.

I posted some questions relating to Tim's truly impressive book. I
hope someone would like to comment on them.

I have no idea what that means. Did some words get lost in transmission?

> I'm not even reading the above two posts from Stereo and Randy.

You are permitted to read or not to read what you like. It isn't that
you /can't/ read those posts, because you then wouldn't know about them.

I haven't read the book yet; sorry.

Sorry for you. Why not use the opportunity to tell us about the
differences between the groups? I could even be interested to join your
group, but at the moment I can't see the point.

I still wonder what your real intentions are...

Still, regards
