Hi, I have an interesting problem: most people use accelerometers to sense orientation and thus measure the DC output value. What I'm trying to do is sense higher frequency vibrations (3-10 Hz). The accelerometer will also be slowly changing orientation so the DC offset will be changing with time. Right now I'm using a digital high-pass filter on the signal and while it works it introduces some unavoidable phase shift. See: http://tinyurl.com/3zpgez9 Just want to check with any mechatronics gurus out there to see if there are any better ways to eliminate or subtract the DC offset from my sensor. Thanks so much!
