Well, be that latter point as it may. Chris, do you have a good
textbook or tutorial reference for this stuff at hand? I happen to be
concerned with this kind of problem but find it hard to get hold of
efficient learning material on DSP fundamentals such as sampling
issues (that 2.15 is not really intuitive).

Sorry for posting off-topic.

Cheers,
