Now, this is a really dumb question, but in sensor datasheets, I have noticed that all the recommended LP Filter cutoff frequencies never seemed to match up when I calculated the RC time constant using their recommended values of R and C. It's just recently I have realized it's always been off by a factor of 2*Pi.
Now the time constant is T = RC
I have always used f = 1/(RC)
The datasheets use:
f = 1/(2*Pi*RC)
Where does this factor of 2*Pi coming in?
