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.
