3.3.2.1.5. Center Spectrum Line
Based on spectrum analysis. Identification of the spectrum lines rising out of the noise and selection of the center
one. Used for acquiring a remnant IF carrier, PM modulated by a sub-carrier or a PCM signal, with any
modulating index up to carrier disappearance (m = 2.406 radians). Not available for PM PLL BW below 10 Hz.
