To whom it may concern:

Dear All,

I am a biologists who is entering the world of matlab and I am having  
great difficulties with it. I am writing to you in order to get some  
constructive help and guidance.
Firstly, let me explain to you what I do. I record non-invasively from  
pregnant women's abdomen. I obtain a signal recording which is sampled  
at 900Hz. This recording contains at every time point a considerable  
amount of all three traces (maternal ECG, feotal ECG and maternal  
EHG). I need to be able to separate them from each other and obtain  
one file for each of them. I know that maternal ECG QRS amplitude is  
at 150microvolts and the foetal ECG QRS amplitude is at 30 microvolts.
Is there any way of performing the above separation?
Thank you

Eleftheria
