So does this new question rule out the cases (previously

not lumped capacitors.


No, but they are an electrical 1/4WL, not any
other length. The electrical length of a stub
is whatever it is. If it is not 1/4WL, it is
some other length. Why is that difficult to
understand?


Well, I know what I mean by 1/4WL and in my
definition there is no way that (46.4 + 10) = 90.

However I am trying to help you articulate your
definition in a way that is sufficiently precise
that I can use it to determine what you would
consider to be 1/4WL. Unfortunately, at the
moment, it is sufficiently fuzzy that the only
way to determine if something is 90 degrees
(according to your definition) is to ask you.
The need of an oracle to answer such questions
is not the basis for sound science.

Tautologies such as "If it is not 1/4WL, it is
some other length." do not further the definition,
but are good if you want to keep the job of
oracle.
