sampling frequency

A Dictionary of Earth Sciences | 1999 | 498 words | Copyright

sampling frequency (station frequency) The frequency at which a data set is sampled is determined by the number of sampling points per unit distance or unit time, and the sampling frequency is equal to the number of samples (or stations) divided by the record (or traverse) length. For example, if a wave-form is sampled 1000 times in one second the sampling frequency is 1 kHz (and the Nyquist frequency 500 Hz); if a traverse is 500m long with 50 stations, the sampling frequency is one per 10 m.
