eliminate 50Hz noise in ECG..
-
hi i am student.im doing research about development of adaptive digital notch filter for the removal of 50Hz power line noise in ECG.i have a sample of 50Hz noise of ECG..now i need to call the file in mathlab..how must i do it?im very new to mathlab..please help me..

Probally the best place where put this question is on the mathworks forum. However to load that file you have write some code , look at functions like fopen, fclose and fread.. Is it a text file or binary? do you know how it is written? Sometimes some functions are yet implemented: if it is a .wav the functions are ready in matlab.

the file is in decimal(negative and positive)..the noise signal is created in excell..should i use the fopen,fclose and fread for this type of file?

Of course you can. with that functions you can open every file type, the problem can be if you know the file format, but this time I'm thinking that it is an ASCII file so there isn't problems. You will need to functions like fscanf to read numbers from file. All this functions can be used also in a simple C++ program, but in matlab you can find ready filters and display tools.:)

To get your data from Excel to Matlab you can simply save as a .csv file and read into Matlab using the textread [^] function. There are other ways, check the documentation.
