source code to eliminate power line noise frm ECG signal

im doing research about eliminate noise in ECG signal..so that im looking for source code which will eliminate the 50Hz power line noise from the ECG signal.any programming language also acceptable..but im more familiar with C language.please help me..

couldnt you write a filter to do this ? Also have you considered using matlab. I do recall the DSP library within matlab is very extensive when it comes to filter design. The article below refers to using a Finite Impuluse Reponse filter for the noise removal from ECG http://www.eng.nus.edu.sg/EResnews/0410/sf/sf_7.html[^] Also if you find converting the transfer function of a FIR filter into code difficult then try this book http://www.dspguide.com/[^] It provides psudeocode, should be easy enough to convert to c.

thanks for your message..i have no background in matlab..so my lecturer asked to go for c language..i couldnt open the link of the article you'd given to me..i went through the dsp guide..my reserach about development of adaptive digital notch filter for the removal of power line noise from biomedical signal(ECG).

I assume you are doing a paper in digital signal processing then doing it without matlab is a crime. Matlab offers you a much better environment for signal processing algorithm development and analysis then C would. Try this link for info on notch filter design for removal of a 50hz signal using matlab. http://www.dsprelated.com/showmessage/57537/1.php Asking someone to give you source code on forums wont make you magically complete your project therefore you need to start reading some IEEE papers on the adapative digital notch filter and figure out how to implement it. That's where the power matlab comes into play, it has built in routines to allow you to do the mathematical aspects of filter design alot easily. Personally, I think your lecturer suggesting to do it in C doesnt really understand the concept of prototyping all too well. The issue is that if you do it in C you will have to do all the mathematics all over again whereas in matlab most of the mathematics are standard routines which you call to make your algorithm work. Learning Matlab is worth while because the concepts of DSP is alot easily explained and learned through matlab then any other platform. Good luck

so you finally went down the matlab part aye. What made you change your mind ? Attempting to write either Laplace Transforms or Fourier algorithms in c# must have been royal pain in the a$$ right ? Ofcourse Matlab can do circuit analysis, provided you have Simulink installed with your matlab installation and the corresponding blockset. I dont know which blockset in simulink does circuit analysis as I havenot touched matlab in 4 years. Have you tried looking up the Mathworks website ?
