1. A method of load-shedding in a system having a plurality of signal sources, said method comprising:

  • a. for each signal source Si selected from a set of sources {S1, S2, . . . }, each source having state pi,k selected from a set of states {p1,1, p1,2, . . . , p1,N;

    p2,1, p2,2, . . . , p2,N;

    . . . }, wherein i is an integer greater than one, N is an integer not less than two and k is an integer from 1 to N;

    i. obtaining fractions fi,k, wherein each 0≦

    fi,k<

    1 is a fraction of a signal from source Si to be discarded if source Si is in state pi,k; and

    ii. determining respective state pi,k of signal source Si based on the signal from source Si; and

    b. for each source signal Si in determined state pi,k, discarding fraction fi,k of a signal from source Si.
