Abstract:
1. A method for protecting a binary signal against transient disturbances, said binary signal having a first state or a second state, the method comprising the acts of: generating a duplication of said binary signal for use in protecting said binary signal (“a duplicated binary signal”), wherein the duplicated binary signal has a first state or a second state; providing an output signal that has a first value when said binary signal and said duplicated binary signal are both in the first state for at least an initialization time duration, and the output signal having a second value when said binary signal and said duplicated binary signal are both in the second state for at least the initialization time duration; maintaining said output signal value after the initialization time duration when said binary signal and said duplicated binary signal are in different states; whereby said output signal is insensitive to perturbations affecting one of said binary signal and said duplicated binary signal at any time following an instant at which the output signal has taken one of said first or second value in response to a change of state of said binary signal and said duplicated binary signal.
