This post might have nothing to do with any knowledge about DSP, however I simply found it so hard to keep myself afloat in the ocean of DSP. I held an EE degree, but DSP was something I didn't like very much in my school days. Well, I have to use it in my current work. And it's painful, since I haven't used it for a few years. To get a fresh start, I grabbed Mr. Lyon's book and had a nice studying experience. But after I continued to solve problems in my O&S textbook, I made mistakes now and then. Since I didn't have much time for self-studying after work, I hoped that I could work out the problems as fast as possible. However, if I rushed, mistakes flushed. And they're simply basic problems! My brain just didn't synchronize well enough with my pencil... Anyway my DSP life must go on. I hope the following prayer help: I pray that I may persistently carry out my linear time-invariant exercises every day. I pray that I may survive in Fourier transforms and sincs.
Self-studying kills!

I didn't have a particularly easy time understanding convolution in my first encounter with it, and I didn't really like studying z transforms. The encouraging thing is that those things became almost (*almost*) fun to me as I studied them more, became comfortable with them, and started to use them in real problems.

But would there be a large enough market to make it economically viable? Heh, I'm into DSP as a hobby rather than as a "student" or a practicing "professional".

Interesting, how many people have the same trouble with DSP when they encounter it initially (I never liked it at engineering school either, learnt some later, and am now trying not to lose touch with DSP). If there's going to be a solved problem set addition to "Understanding DSP", I'll be one of the first people to buy it :-).

Youngsters have > is so easy. :-) > > Regards, > SteveThe only class I got a C in was digital electronics: 1 semester, 3 credits (out of 156). In those days, sweep circuits came under that rubric, and I learned about bootstrap ramp generators and phantastrons. Eccles-Jordan bistables and such were all done with tubes. Oh, well.
