Hi This post is admittedly a little nit-picky, but there seems to be some disa greement over the correct alternate terminology of Cauer filters. Most tex ts refer to ?Elliptic? filters. However, the term ?Elliptical? fil ter 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. O pinions are welcome.

Except if you build it inside a rugby ball, in which case it would be an ellipsoidal filter. Maintain focus, and ask your directrix. ;)

Or, in extreme cases, your dominatrix.

My dominatrix says "get away from that computer screen and take out the gar bage." The directrix is strangely silent. After that slap upside the ear hole, it's difficult to maintain focus. Jon Lark
IMHO this is just another dyslexical discussion.
Failure does not prove something is impossible, failure simply
indicates you are not using the right tools...

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.

I love to cook with wine. Sometimes I even put it in the food.
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?

It is elliptic, for sure.
