所以频域的基本单元也可以理解为一个始终在旋转的圆。 Fourier series square wave circles animation.gif [Fourier series sawtooth wave circles animation.gif] 介绍完了频域的基本组成单元,我们就可以看一看一个矩形波,在频域里的另一个模样了: 这是什么奇怪的东西? 这就是矩形波在频域的样子,是不是完全认不出...

Below: the pointwise error at an interior point (red circles), singular endpoint (green crosses), and nonsingular endpoint (blue square) using Fourier extension with T=2 (full lines) and Legendre series (dashed lines) against the number of degrees of freedom, N. The black dotted lines ...
The possible Weyl-Kuznecov sum formulae for latitude circles H = Hϕ0 thus depend on the two parameters (ϕ0, mℓ). The first corresponds to a latitude circle, and the second to a ladder in the joint spectrum. It is better to parametrize the ladder as μmℓ = c as ...
i.e. it would not look like a tsunami wave. Therefore, I think that each extraction is a plane wave, not a harmonic. In two dimensions, you can use a Fourier series which is made up of plane waves to represent a 2-d function (i.e. a grayscale picture), by this equation: [tex...
Cd concentration* represents the chemically-measured Cd concentrations, and is denoted as filled circles; different filled colors denote varying risk grades (for example, red indicates that the Cd concentration of wheat grain reached or exceeded the threshold value of Grade V). According to the resu...
an image of an object to be recognized is input onto the optical axis by the imaging device 1. After a series of processing steps described above, information on the object of recognition which is to be formed on the surface of the hologram dry plate is subjected to coordinate transformation...
