I'm working about torsional vibration , I use a pic-upin front of flywheel :
what is the relation between : angolar resolution , number of teeth , sample rate ...
thanks in advance

RE: torsional vibration

See the FAQ for this forum. I particularly recommend the Agilent pdf, and a B&K book called Frequency Analysis.

RE: torsional vibration

It depends on your equipment and post-processing.  We use inductive probes that give an approximate sine wave for a constant wheel speed.  Demodulating that signal (using hilbert transforms and filters in Matlab) can allow a resolution comparable to the sample rate - much higher than the tooth-passing frequency.
