Practical Considerations of Accelerometer Noise

From Endevco Corporation
 

 

This paper is written as an overview on low-noise piezoelectric accelerometers and will review when and where low-noise devices are needed as well as the engineering tradeoffs made during the design of the device.

Noise can be defined as any undesired signal. This paper will limit the discussion to noise generated
by the electrical and mechanical components of the accelerometer, the amplifier and cables.
