1 Current work

a) Martin has announced the project plan is approved. The web page is updated and has been improved with two examples of sequences from the Jerry Springer show that is either modified or unmodified. Martin has also visited us in the laboratory. He said that our work was good and inspired us with some new ideas.
b) The detection part of the complete solution is implemented in the DSP. The beep has also been replaced with silence. After a validation, we were satisfied and could proceed with our next phase in the project.

The short of memory in the DSP seems to be no problem since we already has stored almost as much as we need and we have no problem so far.

After validation of the detection part we have almost implemented the first complete version of the solution. Some details are left like: matrix multiplication, toeplitz matrix, the complete AR-library, etc. The big problem left is that the sound we generate in the DSP doesn’t sound a bit like the sound generated in Matlab. So far we have no idea what so ever why.
c) Our first complete version of the solution in Matlab is done and works correctly. We have also started to modify and improve this version. We have built a detection method that can detect whether it’s mostly talk in the sound or not before the beep. If there is mostly talk we should replaced the beep with a very silent sound.

Not all the fixed AR-parameters are decided optimally. But all documentation of the solution is done except the detection part.
 

2 Deviation from project plan

So far we are a little bit ahead the plan.

2.1 Measures taken

We try to improve our work.

2.2 Suggestion on solution

We will make a clear priority list of what we should do in the future. This is a new way to describe how we will proceed with our work (see chapter 3)
 

3 Preceding work

This is a priority list of what we should do until the project is completed. Some tasks have equal priority since all project members work parallel with different tasks. Everyone should make sure that the tasks with higher priority are taken care of before he starts with the tasks with lower priority.
 
 
 

Priority	Task	Due date
1	Find out why the solution in the DSP doesn’t agree with the solution in Matlab. Fix the problem!	00-04-10
1	Weekly report written and web page updated.	00-04-06
2	Document the detection theory.
2	Build the last parts to have a first version of the complete solution in the DSP. This mainly means make matrix multiplication in C-language.
3	Complete the first version of the solution in the DSP, in a way that would be satisfying to present at the end of the course.
3	Write a first version of the final report.
3	Improve our complete solution with:  · The replacement sound should have no constant variance.  · Adjust our solution so it will work when you don’t know the frequency of the beep.
4	Build test cases that prove that our solution is the greatest ever.
4	Make presentation material:  · Slides in Power Point.  · Posters for trade fairs.  · Practical presentation (test case).  · Webb presentation.
