Noise amplitude increases as sample rate increase What you say about time averaging could be the case - that would mean that we have a lot of noise intrinsically in the collection. Then would that mean theoretically there is a sample rate if we go above which, the amplitude would stay the same? |

Noise amplitude increases as sample rate increase Hey Colin, so its called a load cell: basically its a probe attached to the arm of this machine which slowly (.1 mm/sec) moves downward into the material while simultaneously measuring resistance from which it determines the reaction force (how this works exactly i'm not sure). The machine is attached to a computer which allows us to select the sample rate. I think the measurement happens at the same rate but the sending to the computer happens at a faster rate when sample rate increases (i think?). |

Noise amplitude increases as sample rate increase Thanks for the answer...The question that I'm wondering is not how to overcome this..but why it happens? Is there a reason that the amplitude should change when the sampling rate is changed? |
