  2. Bessel function - Wikipedia

    en.wikipedia.org/wiki/Bessel_function

    Another definition of the Bessel function, for integer values of n, is possible using an integral representation: [7] = ⁡ (⁡) = ⁡ ((⁡)), which is also called Hansen-Bessel formula. [ 8 ] This was the approach that Bessel used, [ 9 ] and from this definition he derived several properties of the function.

  3. Bessel polynomials - Wikipedia

    en.wikipedia.org/wiki/Bessel_polynomials

    In mathematics, the Bessel polynomials are an orthogonal sequence of polynomials.There are a number of different but closely related definitions. The definition favored by mathematicians is given by the series [1]: 101

  4. Jackson q-Bessel function - Wikipedia

    en.wikipedia.org/wiki/Jackson_q-Bessel_function

    In mathematics, a Jackson q-Bessel function (or basic Bessel function) is one of the three q-analogs of the Bessel function introduced by Jackson (1906a, 1906b, 1905a, 1905b). The third Jackson q-Bessel function is the same as the Hahn–Exton q-Bessel function.

  5. Bessel beam - Wikipedia

    en.wikipedia.org/wiki/Bessel_beam

    The mathematical function which describes a Bessel beam is a solution of Bessel's differential equation, which itself arises from separable solutions to Laplace's equation and the Helmholtz equation in cylindrical coordinates. The fundamental zero-order Bessel beam has an amplitude maximum at the origin, while a high-order Bessel beam (HOBB ...

  6. Sinc function - Wikipedia

    en.wikipedia.org/wiki/Sinc_function

    The only difference between the two definitions is in the scaling of the independent variable (the x axis) by a factor of π. In both cases, the value of the function at the removable singularity at zero is understood to be the limit value 1. The sinc function is then analytic everywhere and hence an entire function.

  7. Bessel filter - Wikipedia

    en.wikipedia.org/wiki/Bessel_filter

    The roots of the third-order Bessel polynomial are the poles of the filter transfer function in the plane, here plotted as crosses.. The transfer function of the Bessel filter is a rational function whose denominator is a reverse Bessel polynomial, such as the following:

  9. Hankel transform - Wikipedia

    en.wikipedia.org/wiki/Hankel_transform

    The necessary coefficient F ν of each Bessel function in the sum, as a function of the scaling factor k constitutes the transformed function. The Hankel transform is an integral transform and was first developed by the mathematician Hermann Hankel. It is also known as the Fourier–Bessel transform.
