Day4

Day4 - filtermania

Filtering is fun! We got started with creating several filters and get used to implement them in scripts and paramate them. We finally got some "dirty" sounds with the challenge to clean them. I have to say it's fun to see results of our work.

done:

• Excercise 4 - filtering Click me for the Teamsheet
   
• Created Filters (Bandpass, Bandstop, Highpass, Lowpass)
  
• Implemented those Filters in Matlab
• Cleaned out the noises in the sailor sound
   
• worked: 7h + (20h)  = 27h

  learned:

• how to use the fdatool creating filters
  
   
• implementing those filters in a script
  
   
• analysing data looking for noises
   
• designing filters and implement them to get rid off those noises

  
  

   to Do (next)

   
• finish Day3 Question 11
   
• prepare for project
   
• getting difficile knowledge of several filters
  
• exact dB filtering ( using exact surpressions / magnitudes )
