Gyro Filter

[crazycliffy]

This is like a bandpass filter with cutoffs to allow
ranges within the 47Hz and 185Hz frequencies.

Where did you get these numbers from? I look at
the www.systron.com mfg website, and they don't
spec these numbers.

Are these included with the actual gyro for 2003?
I don't have the 2003 gyro yet, as I'm doing some
prototyping work with the 2002 model.

Also I did a search using chief delphi (CD) && google.com
and didn't get the numbers you spec'd.

thanks for any clarification.

The documentation on the gyro and interface circuitry includes a filter. If you read carefully and follow the circuit, you will see the recommendation of a 47HZ high pass filter and a 185 HZ low pass filter is part of the interface amplifier. In the car example it is mentioned that the gyro does exhibit some output from the up down motions of the vehicle without these filters in place. Still filters are chosen for specific applications, a head mounted sensor for interactive game play may require a 0.1Hz to 10Hz filter to eliminate small high frequency head movements from affecting the needed head turning data.
