About rendering physical reality

  1. Aug 29, 2008 #1
    Hello all,

    as far as rendering physical reality, isn't sampling frequency the main thing ?...

    I don't understand your question, rendering physical reality and sampling are two different things. Samples can be used to validate models that render physical reality. The temporal resolution is important depending on the dominant frequency of the system. Your sampling frequency should be twice that. I don't know why this should be the main thing. spatial resolution and range are just as important. I you try to measure pressure oscillations of 0-1000 psi with a 0-10 psi transducer your in trouble regardless of the transducer's time constant.
