The question is whether a circuit that operates at voice
rfrequencies has an effect at radio frequencies.

Do you know what intermodulation distortion is?

Yes I do.

Look it up.

No need. Are you suggesting that passive components and networks
can create it ?

Ferrite is non-linear at higher magnetic flux levels and is used for
the filter inductors. I am not saying that in the case of ADSL
filters that this is necessarily a problem but the potential exists
in a poorly designed or manufactured filter for IMD.

I agree with the issue about design (which Peter Crosland refuted).
The manufacturing process won't influence it though.

Please show where I have done this? I repeatedly said quite the opposite
i.e. that poor quality filters do not perform as well as good ones.
Obviously the design is a part of the quality as well as the physical
quality of the components just as the assembly of them is. It does not
matter how good the quality of the components is if the basic design is
poor. In the case of the cheap ADSL filters the design is so poor that even
if they were made of top quality componenst they would still not perform as
well as a well designed one.
