hi
i m using EEG signal for the filtering purpose. and i have got these problems, please help me to solve me , please give your answer with matlab example, so that i can use it in my code also....
problems;
1- there are so many frquencies in the data(.txt) file ,i have got from internet, sohow i can see my signal frquencies????
2- if i directly jump to filter my signal , how i can normalize it..???
3- What is the basic concept behaind the discrete range of -fs/2 to fs/2, and
0 to fs, this(-fs/2 to fs/2) when use gives result in hertz ,while 0 to fs/2 gives result in radian/sec.
best regards
