Hi,

"My rule of thumb is to make the hardware adequate, if at all possible. You
don't say what resolution you need, but at 1.6kHz you have quite a choice
of ADCs. How much you have to do in software depends on the hardware you
have and the goal (neither of which is stated... :)."

The requirement is for a large volume (100k/annum), v.low cost product
which blurs the edge of making the hardware "adequate" as opposed to using
a modicum of cleverness. I was asking on behalf of a colleague and I
believe his requirement is that a resolution of 12bits (14 would be
better!) over a 0-5V range at the sampling rate suggested. The current
hardware has one 10-bit converter AFAIK.

My colleague is digesting the replies I have forwarded so far and will have
a reply soon (or so he tells me ;-)

Thanks to all respondents,

Regards,
Dan
