Probably not. Depending on the A-D it will give an averaging effect of any signal changes that happen within the sampling period, which will remove some of the higher frequencies, but inconsistently and incompletely. That's best case. Worst case the A-D will give a completely nonsense reading if the signal changes quickly enough.On Sun, 17 Nov 2002 10:58:52 -0800, David Weinshenker <[EMAIL PROTECTED]> wrote:And I'm not at all sure that the accel data are to be trusted... when we do the all-up static firing, I wanna borrow back my 'scope from the gizmocopter team and put it right on the cable from the chamber pressure transducer. I think there may be higher frequency stuff going on in there, and we're not seeing a true image of it in our A/D sampled readouts.Total amplitude should be the same, though, right?
I haven't seen your circuit though but if you've got any sense you'll already have a low pass filter on your A-D converter; even a simple RC filter.
