No. It means you are approaching DSP from the wrong angle. Don't get into DSP for its own sake. Learn and use DSP because it serves some utilitarian purpose. It's like banging a nail with a hammer: A total ridiculous skill when seen in isolation, but a skill essential to woodwork. In other words, you don't learn to use a hammer because you think it's fun banging on stuff. You learn it because the skill is necessary to achieve some larger goal. So instead of searching up the tool DSP, search for applications you think are fun. Then learn whatever skills are necessary to get good in this activity. Ah, yes: Don't quit your current job. 'Work' is about making a living and obtaining an income. Quite essential to most people. If you want 'fun', 'interesting' and 'satisfaction', look for a hobby. Rune
Thank you all for your quick responses. Its very encouraging for me to know
there are a lot of professionals out here who are willing to take some time
out to answer some really basic questions.

Unfortunately for me, I got lost quite a bit between posts. Maybe i should
do a little more reading and browsing, get some understanding of the
industry as to why..where..and how things are used. But, i surely will be
back for a few tips & suggestions. I understand people are here to discuss
more complex real world problems that you face, hence i will try to refrain
myself from posting any 'homework problems'.

thanks

this is why i would like to know what a DSP engineer does so it helps me understand where i stand as to.., am i taking the right path by trying to learn DSP. I came across a couple of links like...http://www.dspguide.com/ch1/2.htm (Here a few applications of DSP are described at a 'high level?'.. If i may call it so) It would be helpful, if i can come across links that explain DSP, maybe in the same manner as above, but a little more in depth. Maybe, that way i could be introduced to, where in systems does DSP come into play, & what was achieved by going the DSP way. I am not necessarily looking for a short description of the system, like in the link above.

No, you are not. We are saying that you should find some topic you want to learn how to work/play with, and *then* learn the tools and trades necessary to become good or successful at this activity. You seem to have fallen in love with the tool DSP, and are looking for applications. Don't do that. Would you choose to become a carpenter just because you like to hit things with a hammer? Rune

Rune, I don't agree. I like doing DSP and Math. If there is not DSP in the job I won't take it. I started learning DSP in an MSEE (DSP concentration) program almost 30 years ago, then I have worked for various companies (direct, contracting, consulting) that worked in vastly different application areas, were I learned about the specific application areas, learned what additional DSP or other information I needed to know, and with a single exception, primarily worked on the DSP part of the job. The tools are facinating. Learning to apply them is interesting. What they are applied to just has to be interesting. Dirk

So you got into DSP in the mid/late '70s? In those days DSP was a new and emerging field, computers were the stuff of specialists and a musician had to actually know how to play a musical instrument. What worked for you 30 years ago, when you were a young and curious engineer, doesn't work today. The fact that your approach still works for you is down to your age and seniority alone, not the field you chose for a profession. Times change. Believe me, I'm old enough to know. Even, as it seems, if I'm your junior by some 10-15 years. Rune

Hello Dr. Rune,

Glad to see you again. Have you been in the sea all that time?
What a pleasure to see the real character here.

Cultural thing indeed. "We don't have bad students, we only have good and average students". And btw, there is no such word in English for something that can be explained as a combination of platitude, triteness and vulgarity. That simply means they don't see this as a problem :-) I think there should be a limit of how low do you want to go. Especially as this is comp.dsp, not alt.idiot.student.help. The one who asks a question should at least know what he is asking about. VLV

No, unfortunately. It seems lots of activity at sea has more or less ended, due to the banking crisis. I had to refocus some of my work, from interesting long-term stuff to can-provide-billable-services-in-a-few-months kind of things.

Reminds me of a Norwegian statement a few years back: "We want everybody to be above average!"

Is there such a term in Russian? One of the guy's I met off-shore taught me a word that might be close. The best seaman I ever met; grew up in the middle of Siberia. He was 17 or 18 when he saw the sea the first time. I *think* the word was 'njevjadzde' or something like that. (This was three years ago; I haven't heard or used the term since, so I might be way off.) Anyway, the term was more derogatory than 'njekulturnik'. 'Njekulturnik' was, according to my friend, a result of up-bringing and is thus an involuntary status. This other term was apparently more about attitude, and thus about personality.

It's amazing what can be learned from mere etymology.

I'd settle for that those who don't know, know that they don't know... Rune

Interesing. So, did they abandon the oil exploration, or just changed the approach?

Huh. This is one of the things that broke the West. "You can't give everything to everybody, because there is too many of everybody and too little of everything", as my friend used to say.

"poshlost"

"nevejda" - ignoramus "neveja" - lout

"uncultured"

The behavior of a person is the responsibility of his own. Blaming on something from the past is no more then a convenient indulgence.

Your friend has a good literature Russian.

BTW, in Russian, there is no word for "privacy", and this leads to the correct conclusion, too. I wonder what are the etymological differences in Norwegian. VLV
