Greetings Gents,
I'm looking to fabricate a 1 HZ to 20 HZ active bandpass filter for an
oddball active vibration dampening project I'm playing with. Signal
source is a MEMS accelerometer -> bandpass filter -> amplifier -> mass
driver, with the goal being to reduce the dampening time of a 2 meter
long, 400mm diameter metal pipe.
The primary requirement for the filter is that the input and output
must be in phase with each other, is this going to be a problem?
Secondarily, it would be nice for it to have a rather steep cutoff
(24db /oct or better).
Any thoughts?
Take Care,
James Lerch
