Hi everyone
I am suppose to build an electronic stethoscope on "multisim" software
I found the circuit in one of the threads here but I don't know why exactly these stages were used
Can you please tell me why ?!
also, I wanna ask about the input for the circuit. I've been used a microphone but I want to know which frequency best to select that can mimic the heart beat sound?!
This is the circuit I built
thanx in advance
