Example sentences for: periodogram
How can you use “periodogram” in a sentence? Here are some example sentences to help you improve your vocabulary:
The most common non-Fourier-based technique currently in use in chronobiology is the " chi-squared periodogram" [ 41 42 ] . Although serious objections have been raised in consideration of the periodogram (discussed from varying perspective by Whittaker and Robinson [ 42 ] ; Kendall, [ 43 ] ; Dowse and Ringo [ 39 44 ] Enright [ 46 ] , we continue to employ this method along with others discussed below.
The derivation of a given coefficient has no effect on any others [ 45 ] . A plot of the Fourier coefficients as a function of frequency or period yields a spectrum indicating any periodicity in the data and its frequency, the true periodogram (this use of periodogram is not the same as the Chi-squared periodogram traditionally used to evaluate circadian rhythms data [see [ 44 ] ]).
The area under the curve of the periodogram equals the variance in the data, which has now been partitioned according to the frequency and moved from the time to the frequency domain [ 37 ] .
The periodic pattern of eclosion (emergence of the adult at the end of metamorphosis) and the pattern of adult locomotion (Figure 1a,b) are classic examples of circadian rhythms, which are typically analyzed by application of periodogram functions [ 14 15 16 17 ] . Figure 1cand 1ddisplay examples of daily molecular rhythms for a whole fly and a pair of dissected wings, as reported in real time by luciferase-encoding DNA fused to regulatory sequences of the period (per) clock gene; these gene-product fluctuations have been analyzed using functions other than periodograms [ 10 18 ] . Drosophila rhythms are also evident on other time scales besides circa-24 hours.
We tend to use MESA and the correlogram for luc data and we also include the correlogram and chi-squared periodogram analysis for locomotor activity or eclosion.
