The Nyquist frequency for irregularly spaced time-series: a calculation formula
暂无分享,去创建一个
Eyer & Bartholdi showed that the Nyquist frequency of irregularly sampled time-series can be very high. In this paper, a calculation formula for the Nyquist frequency is presented. In practice there is an upper limit of 0.5/Δ on this frequency, where A is the best accuracy with which time is recorded.
