1. A method comprising:

  • receiving an input;

    combining the input with a delay in a combiner;

    triggering the output of the combiner;

    buffering the output of the combiner to produce a buffered output;

    inverting the output of the combiner to produce an inverted output;

    applying the buffered output to a first isolator to produce a first isolated signal;

    applying the inverted output to a second isolator to produce a second isolated signal;

    comparing the first isolated signal and the second isolated signal using a window comparator;

    applying an output of the window comparator to an R-S flip-flop latch;

    filtering an output of the R-S flip-flop latch;

    buffering an output of the filtering; and

    transmitting an output of the buffering.
