We use ADIS16265 and ADIS16364 gyros, depending on our needs. I am trying to calculate gyro noise performance based on our choice of filter taps, and SMPL_PRD settings.
I know that output noise = noise_rate_density X sqrt(equivalent noise bandwidth)
However, I don't know how to calculate equivalent bandwidth for a Bartlett FIR with taps. Also I don't know how the math works with the SMPL_PRD setting and equivalent BW when using the Bartlett filter.
Thus I am unable to calculate output noise for our choice of settings versus alternative settings. I've tried but haven't been able to discover the math behind your output noise values on the 16265 datasheet (16364 doesn't have any tap examples on datasheet).
