Example sentences for: periodicities
How can you use “periodicities” in a sentence? Here are some example sentences to help you improve your vocabulary:
When there are elements within a signal that interfere with the extraction of periodicities in the circadian range (or any range of interest), the raw data often need to be filtered for further study.
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.
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.
These trends appear as very low frequency periodicities and can also interfere with the assessment of 24 hour periodicities.
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).
