I would like to inform everybody that you are losing me as a contributing member of this community. I cannot stand the hostility against non-engineering (but rather math oriented) approaches to DSP and the general culture of academic discourse that is practised here anymore. I hope those who are contributing to this climate understand who they are. I have always been open for discussion, but I am not open to ridicule and arrogance, as I have faced it here regularly. A simple rule could make things so much easier: If you don't understand it or it's not meant for your but someone with a different perspective, please just ignore it. There is not need to fight it.
Enjoy your time here. I will miss a few contributors who are able of civilised exchange and discussions and who have preserved an open mind. Please keep it like that!
Regards,
Jazz
