Bessel

Description

A(t)=A_0J_0(2\pi\nu t+\phi)

where,

A_0 is the amplitude,

\nu is the frequency of oscillation (MHz),

\phi is the phase at t=0,

and J_0(x) is the Bessel Function of the first kind, its expression is given by:

J_0(x)=\sum_{l=0}^{\infty}\frac{(-1)^l}{2^{2l}(l!)^2}x^{2l}.

A plot of Bessel function.

Properties (fitting parameters)
