Hey guys have a small exam comming up, and I've got few questions I am not too sure of could someone take a look and guide me in the right direction.
1. An accelerometer in a fall sensor system is band limited to 5Hz. If the system is operated at 5 times oversampling, what sample rate will be used?
I assume thats 5Hz * 2 (the nyquit rate) * 5 ?
2. The same sensor incorporates a three axis accelerometer and three single axis gyroscopes. If the sample rate is now 100Hz and the samples are 16 bit per measurement channel, calculate the required bit rate.
Is someone could explain how to go about getting the answers to those I would be very happy, thank you in advance.
