If the accelerometer samples at 50Hz, how could there be an antialiasing filter?

What would that filter look like?

Anything physical which dampens higher frequency oscillations would act as an antialiasing filter.

What sort of size do you think something that would damp 25Hz vibrations in something that weighs a gram or two would need to be?
