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