REFLECTOR:Re: RVDT/LVDT Conditioner

[Joe]

Brian,
Thanks for your reply.  The best price on a conditioner I have found is a
unit designed for AI at about $125 per channel, so anything better that that
would be interesting.  I have also found an Analog Devices chip for about
$25, but don't really want to spend the time building a board when I am
trying to spend my time building an airplane.

What do have in mind when you mention DSP (I presume referring to Digital
Signal Processing.)  In my case I already have the gyro with RVDT sensors on
each axis, so the conditioner seemed to be the way to go to bring attitude
info to the CPU.

Joe
