    it doesn't make sense...its up to designer at which order he wants to use. Increased order normally gives sharp cut-off,which is nearer to ideal filters.
    and some dsp processors can use up to 100th order filter.

    (though theoretically you might 've studied only upto 4th order for different windows)
