hi all electronics experts and pros.. i need some explanation on my ecg circuit.
this is my ecg circuit diagram.
please kindly help me as i am not very sure.
i need advice and explanation
from what i know, op amp 1 is rc low pass filter,
electrode 1 connects to op amp 3 and its a non inverting op amp for amplifying.
electrode 2 connects to op amp 5 and its a non inverting op amp for amplifying.
electrode 3 connects to op amp 6, it is a invering op amp.
what about op amp 2 and op amp4? what are they acting as, what are they use for in this whole circuit? are they also amplifying? i thought op amp 3,5,6 are already amplifying? can and pro explain to me ?
can any 1 also please explain my whole circuit and let me have a better understanding ?
i really appriciate it. thanks!
