Sample rate
Also: sampling frequency, fs
The number of measurements taken per second.
Rate, aperture timing, analog bandwidth, and anti-alias filtering together determine which signal content can be represented.
- Units
- samples/s or Hz
- Formula
f_s = 1/T_s
Example 100 samples/s gives a nominal 10 ms interval.
Common misconception Logging at a stated rate does not prove samples are evenly timed or alias-free.
