In practice, the convolution theorem is used to design filters in the frequency domain. The convolution theorem states that convolution in the time domain is equivalent to multiplication in the frequency domain. The frequency domain can also be used to improve the execution time of convolutions. ...
The real integral representation in (7) of the convolution kernel is much simpler to deal with than the usual contour integral representation along a Hankel contour in the complex plane, which is used in the analysis of more general sectorial problems [26]. This allows us to derive rather cle...
However, although the DCT is closely related to the DFT, the multiplication-convolution theorem for the DCT was formulated much after the corresponding relationship for the DFT. In fact, despite the several attempts to establish this relation [31], a complete and more consistent formalization was ...

The transform of this truncated kernel can be computed easily and is infinitely differentiable by the Paley-Wiener theorem. As a result, a simple trapezoidal rule can be used for quadrature, the convolution can be implemented using the fast Fourier transform, and the result is spectrally accurate...
According to a theorem proved by Heine in 1872, a function that is continuous on a closed and bounded set is uniformly continuous there,1 and then each φx + h is uniformly continuous on the larger disc consisting of all points of the form s + h with s in D and h≤ 1. Hence, ...
image.With the powerful convolution theorem we then developed an interpretation of convolution as the diffusion of information across pixels. We then extended the concept of the propagator in the view of quantum mechanics to receive a stochastic interpretation of the usually deterministic process. We ...
3.This paper discusses the Noether theorem of complete singular integral equation which containsboth the convolution kernel and the Cauchy kernel, and comes up with the Noether theoremwhich is similar to the Fredholm integral equation, the convolution equation and the singularintegral equation.本文讨论...
