A periodic discontinuity requires an infinite number of terms to
resolve.

** No real world one does - since it is band limited.

The real world is continuous. There are no band limited discontinuities.


** Cos there are no true discontinuities in the real world at all.

They are a mathematical abstraction.



A simple fact that counters the insane rubbish you are preaching.

No, I said "A periodic discontinuity requires an infinite number of terms
to resolve.", which is true.


** A simple, mathematical discontinuity has ** infinite** bandwidth.

However, real world discontinuities have limited bandwidth and hence a non
infinite series expansion - so they CAN be exactly represented by a
series of sine waves.


BTW

Allison's Theorem says:

" Iveson is an ass. "

Iveson himself keeps proving the rightness of this theorem.
