- Page 70 ® ® G-Link -LXRS Wireless Accelerometer Node References User Manual Oversampling: In signal processing, oversampling is a technique used to achieve increased signal resolution and better noise immunity by recording readings at a higher frequency than the output of the device being measured. In analog- to- digital conversion, the higher the oversampling rate, the better the recreated analog signal.
- Page 71 ® ® G-Link -LXRS Wireless Accelerometer Node References User Manual Slope: When describing a mathematically linear relationship, the slope is the steepness of the line that represents that relationship on a graph. The equation of a straight line is: y = mx+b, where x is the x-axis coordinate, y is the y-axis coordinate, m is the slope, and b is the offset.
