How can you use “periodicities” in a sentence? Here are some example sentences to help you improve your vocabulary:
Thus, as white light can be filtered to yield any component spectral color, by analogy, specific periodicities within a signal can be easily eliminated using a filter algorithm [ 31 ] . Although it is not our intention to present a formal or rigorous review of digital filters (see [ 36 ] , for example), we will introduce a simple filter and then discuss the slightly more sophisticated Butterworth filter which we use in our studies.
Finally, the pitfall of FFT-NLLS is that the curve-fitting operation associated with a probing sinusoid is sensitive to the presence of other periodicities in the data, variations in wave form from cycle to cycle, and random noise.
For example, ultradian rhythms, periodicities in the range of 5 to 18 h, may be present [for example, [ 27 28 ] ]. While the latter rhythms are inherently of interest [ 29 30 ] , they may nevertheless interfere with the analysis of the 24-hour components of the signal.
It is nevertheless informative to monitor the statistical significance of periodicities; for this we devised a ratio that allows us to track whether or not a specimen is significantly rhythmic, the so-called Rhythmicity Statistic (RS).
Figure 5cshows the application of a high-pass filter, which removed the periodicities greater than 72 hours.
