I am trying to understand how to use the "Rate noise density" spec on a gyro IC. It is quoted at 0.25 degrees/second/root(Hertz). I plan on sampling it at about 100Hz. Is the noise going to be root(100Hz/2)*0.25 degrees/second/root(Hz) = 7.1*0.25 degrees/second = 1.8 degrees/second ?
(edit) It is my understanding that the bandwidth is half the sampling frequency. If this is wrong please let me know.
Any help is appreciated.
If you care the chip in question is Analog Devices ADXRS649.
