ModOsc

Description

Traverse Field sinususodally modulated oscillation. Sinusoidal distribution of precession frequencies about bias e.g. from SDW.

\[A(t)=A_0 \cos(\omega t + \phi)J_0(\omega_\text{mod}t)\]

where,

\(A_0\) is the amplitude,

\(\omega\) is the oscillation frequency,

\(phi\) is the phase,

and \(\omega_\text{mod}\) (G) is the modulation frequency.
