    This post is admittedly a little nit-picky, but there seems to be some disagreement over the correct alternate terminology of Cauer filters. Most texts refer to “Elliptic” filters. However, the term “Elliptical” filter is also used. In my opinion, “elliptic” is the correct terminology, since the pole locations are determined by solution of elliptic functions, whose periods are determined by solution of Jacobi elliptic integrals. Opinions are welcome.

    My dominatrix says "get away from that computer screen and take out the garbage." The directrix is strangely silent. After that slap upside the ear hole, it's difficult to maintain focus.

    IMHO this is just another dyslexical discussion.

    This is the kind of (pseudo)issue that keeps idiots employed. Use what
    you think best and to the devil with rest.

    Very much so, but it inherits from really crappy ESL instruction that does
    not make points about exceptions stated in the codified rules; such as
    "dynamical" instead of the correct "dynamic". Common even in academic
    papers since at least the 1940s. "Lolly, lolly, lolly get your adverbs
    here" class pre-school early grade school over generalization.

    Yes, it is a pet peeve. I only have a dozen or so.

    This is the kind of opinion that keeps everyone dumbed-down. This goes
    right along with the "theory" of education where kids get to make up
    their own spelling of words. Don't want to hurt their self-of-steam!

    Elliptic is correct for the reasons stated. Sheesh. World goes to hell in
    hand basket!

    Why is it that the dumbest clowns always call everyone else an idiot?

    Are you a dynamical doofus?

  10. It is elliptic, for sure.
