Thanks again for the effort. However I'm still not clear with everything. How about that we observe the words instead of phonemes. Let's say our basic alphabet is an English dictionary. Now let's say that i heard the following sentence: "This information theory is quite abstract to...

Thanks for the reply. I see now that I made a mistake in where I used relative entropy instead of self-information. However (back to your answer), it isn't the entropy which is bothering me, but "self-information". The concrete amount we get after the uncertainty is gone and we know...

Hello there. I'm a 4th year computer engineering student who is just at the end of an Information theory class. It was nice, I thought I got a grip on all the concepts and so... But, I tried to explain to my girlfriend today the basics of information theory, and I failed to do so. The...

Hy. I have a problem about correlation depending whether it it observed as a measurement of linear fit of statistical data, and when observed as a relationship between two continuous functions. Is a result of correlation a coefficient (Pearson's product-moment coefficient) or a function...

I got it now. The answer came through the study of Information theory, a bit expectantly. I was mostly That's true, but after a modulation has been done, it gives me the amount of bandwidth. I will draw the the figures soon as soon i get costumed to octave :)

I think I'm getting the hang of it. We're dealing with bands instead of single lines (irrelevant of the modulation scheme) because of the Fourier transform of the modulated signal. For example. the picture i posted for frequency modulation, the process of actually emitting the signal is Fourier...

Thank you for your answers. I was mainly troubled by the image i posted in the previous thread and DSSS (Direct sequence spread spectrum). But now you,ve gotten my a bit more confused with , which is good since that what you pointed is essentially what bothers me. So, let's talk...

Hello there! I have a problem with conteptual understanding of the bandwith od channels that use frequency division multiplexing. How i understand that FDM works: We have a transmitter that transmits on one frequency f and the receiver that listens on that frequency. They can communicate...

Oh well, thank you for your time. I can't say i understand quite, but i suppose time will make it more clear with the study of classical mechanics.

That is a experimental task in which i can measure the angular acceleration together with the force and the lever lenght. What does the J i get by J=F l/ \alpha mean then? How do i get it analytically?

So you're saying that the expression i wrote isn't true? They kind of physically make sense. (never the less, intuition is often wrong :) )

I must say, I'm still not following. :) I got a replay on another forum that J from the point of the big discs center is J = Jbig + 2 msmall l2 + msmall rsmall2 For when small discs aren't rotatable. (l is the distance between the centre of the small disc and the centre of the big disc)...

Thanks for the replay. I didn't understand you quite clearly. Can you please write the equation for the complete moment of inertia from the centre of the big disc when the small discs rotate freely along their axis. I believe it will be more clear that way. Tnx

Hello there, i have a problem with calculating the moment of inertia for the object on the picture. There are two cases I'm observing. In the first case, the obect rotates around the axis located in the center of the big circle, and the little circle can't rotate around the axis located in...

Hello there! I was thinking about jumping the other day. How would one explain jumping by physics. So, before you jump, you always bend your knees. This knee bending, from my point of view shouldn't be analogized with the build up elastic energy, since the force that will cause the jump...
