Abstract
For a Lorentzian channel with a given fifty percent amplitude pulse width, we find closed form representation of the servo burst signal. We then derive the frequency of the servo burst signal that maximizes performance or signal to noise ratio. This optimal frequency depends on the estimation scheme used; that is, whether we estimate the amount of signal from peak, rectified area or matched filter estimator
