How can you use “fourier” in a sentence? Here are some example sentences to help you improve your vocabulary:
This representation is similar to that of a signal by a sum of its Fourier modes.
The harmonic balance method can be used [ 17 ] . The basic idea is to represent the limit cycle by a Fourier series with unknown coefficients ( a
Since it is the relative phase shift between each state variable that is relevant, we assume that θ 1 = 0. The substitution of the Fourier series into the original equations leads to a series of real algebraic equations for the coefficients (not shown) whose solution was obtained using Mathematica.
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 ] ]).
One further method of period estimation needs to be mentioned, as we and others have used it in the past [ 10 18 ] . It is called Fast Fourier Transform - Non Linear Least Squares analysis (FFT-NLLS).
