1. An apparatus for use with a myoelectrode that provides a myoelectric signal, the apparatus comprising:

  • a comparator, electrically coupled to the myoelectrode, for receiving a first signal derived from the myoelectric signal and for comparing the first signal to a threshold signal, the comparator providing an output signal indicating whether or not the first signal exceeds the threshold signal; and

    a switch, electrically coupled to the myoelectrode and to the comparator, for receiving a second signal derived from the myoelectric signal and for receiving a control signal derived from the output signal of the comparator, the switch providing at an output lead an output signal in response to the control signal.
