    [SOLVED] Heart beat sound detection.

    Previously I have used Class AB amplifier in simulation after the instrumentation amplifier and filter to amplify the low amplitude signal, but didn’t have better result, that’s why I am trying with this complex circuit. Here in the simulation I am getting better result than before, but the...

    [SOLVED] Heart beat sound detection.

    Hello Everyone, Below is the circuit that I have simulated in the LT-Spice. Here for the power supply (+11v and -11v), I have used Boost converter. Here the problem is at real time implementation. The input to the circuit is being given using contact microphone and output is being taken...
