Yes, you're right and the problem was wrong. In the right-hand side of first expression, there's also exp(-iwt/2) And the equivalence is proved.

Homework Statement prove that: 1-exp(-iwt)= 2i*sin(wt/2) Homework Equations exp(iwt)= cos (wt) + i*sin(wt) The Attempt at a Solution I attempted to express the exponential into sum of cos and sin and considering t=2*t/2 in order to obtain an argument like (t/2) (using...

In a token ring LAN (IEEE 802.5) what are the differences between "Single token", "Multiple token" e "Single packet"? Thanks in advance.

In the Rfc about MOSPF, is declared that one difference between this alghortim an his "unicast version" OSPF that, while in the former what is important is both the source and the destination, in OSPF what is fundamental is just the destination. Why this statement, if in both case source is...

Nano-----, what means? What is a nanoblade? And a nanospring? I am not an expert about nanotechnology but I would like to understand something more. Thanks in advance.

Thank you. Question solved.

I'm an engineer. What's luminosity? I don't understand the explanation of Wikipedia. Why are physics glad if the luminosity grows up in LHC, respect of last year?

You are right. Huffman code is not used in audio coding. But, Rice code belongs to that category like Huffman one, is used to obtain FLAC format after a particular use of a linear precition filter. If you are interested, look at Wikipedia page about FLAC.

When I wrote last message I did not have any idea. But, lookinf for on books about audio signal processing i found an a grest part called (entropy coding). Entropy is in of the most important concept in information theory and so, I'm studing what this type of coding reale with. Thanks for...

I'm looking for an appllication of Information Theory applied to processing/broadcasting of an audio signal, but i have no idea. Do you know any books where i can look for this subject? Thank you in advance.

In general, if I have a constellation of symbols, how can i calculate the energy por bit? I think I should calculate the area of figure which is formed linking external points in the space signal and divide it for the numer of bit compose the symbols. Right?

In an convergent/divergent lens, how do we consider an object real o virtual?? I thonk is real if it's placed at left of the len and virtual if at right. Right?

Ts=Nss:Nss:length(s); hold on plot(tv(Ts),fo(Ts),'or'); hold off grid on This is the last part of my Matlab macro. I see that it creates a plot using two vectors called "tv" and "fo". I would like to see the plot and this vectors too in my workspace on Matlab. May I use a...

Homework Statement There are three linear polarizers perpendicular to the same axe. To the first one natural light arrives. If the second one rotates with angular speed known and the first and third ones have transmission lines perpendicular {between them}, find the intensity of final light...

If a ray hits a medium with Brewster's angle, reflected light is linear polarized {if electric field way is not parallel to incidence way}. But what does it happen to refracted ray? Thanks you in advance
