    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 ?! :D
    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

    Sounds like a school project to me. Hence moved from The Projects Forum to Homework Help.
