Q Rx Cx Cc Ca Ra V                                                      V

                                                                    -              t

    Where:                                                             Oscilloscope
    Q = Charge produced from applied pressure
    Rx = Resistance of piezo
    Cx = Capacitance of piezo
    Cc = Capacitance of cable
    Ca = Capacitance of amplifier circuit
    Ra = Resistance of amplifier circuit
    V = Measured voltage
