the problem with converging IIR is that either
the IIR or the

exponentially decaying white noise impulse. it makes sense,
I don't understand why. Is it just beacuse the kernle is a bit too long to
be stable, or is there someting more to it than that?
When the converger tries to find the best coefficients by using a recursive
error minimation i dont wonder that i may fail here. A IIR is nothing else
as a differential equation solver. As a result you can only approximate kind
of periodic signals i guess. Correct me if i am wrong, its quite a long time
ago
since i learned about linear system theorie and IIR stuff...
