  • Heart-beat electronic simulator
    Patent number: 3994282
    Abstract: An electronic device for simulating the human heart-beating noise comprises an astatic multivibrator, the output of which is a square wave voltage signal. This signal is given as an input to a differentiating circuit having its output connected to drive a loudspeaker diaphgram. The acoustic wave produced is similar to the human heart-beating noise.
