Our project is to build ECG machine that take 3 point from the human body using electrodes and enter this small voltage to amplification circuit in order to give voltage signal that can be introduce.
So our project depend on amplification circuit ,this circuit contain powerful amplifier which has high gain in order to be able to take signal that can be seen and measured .
Our project its so sensitive because we have high voltage gain and wire and electrodes connect to the human body ,all these component give us
Noise that will be effect to our signal, so now we need very accurate filter that able to remove this noise from our signal without effect it.
After we have accurate signal we will enter this signal to PC in order to be analysis and get the heart rate according to database stored in our program we build it using C# language.
In order to enter this signal to PC we need to convert this signal to digital value in order to be able to deal with it in PC.
This is small introduction about our project we give small idea about our work now we will give the basic circuit for our project and the main structure of the circuit that we used
