Recently, I’ve been ask to write a 30pages study comparing the different types of communication techniques applied to SOHO networks (residential networks). The subject was, in French, :
“Comparaison des différentes techniques de transmission de données, Solutions applicables à l’habitation particulière”.
Well, after some 6weeks of sleepless nite, and coffee doping, here it is, I hope this [...]

In the series of Digital Transmissions Studies, let’s study the following transmission Channel :
We will attempt to define the ideal matrix of the transversal equalizer in a few steps.
Working in the energy meter fields lately, and googling for informations regarding the measure class definition does not help much …
I’d like to clarify what exactly are those two things here, and give you some clues on how to test that on a fresh new design
Those days I am working on the Echelon PL3120 Chip (to make it integrate our products), I having some problems to integrate it properly, here is some hints for you guys if you are trying to integrate them as well (The following information is also applicable on the PL3150 and PL3170, and I guess PL31xx):
Here is the problem:
Given 3 points , and verifying and , and . We want to know what cosinusoidal curve pass though those 3 points like :
Still guessing about it but, I couldn’t find an elegant way to find the minimal hamming distance of a code … till I finally got it !, here it is:
Basically the question falls to find the minimum amount of difference between two different codewords, say you got your codeword which is bit long, systematical [...]
Working on my next practical class (ELE109), I had the impression of something wrong in that text:
Let be the generator polynom of the code, the non systematical matrix can be defined by calculating , , and :
Well, that last one sound wrong … let’s check, it out, we can obtain the systematic [...]
