The power spectral densities of the Transmit Reference doublet (TR-doublet) train and the Reference Sharing doublets (RS-doublet) train are computed with the mathematics presented. It is shown that the PSD of the RS-doublet train has similar characteristics to the TR-doublet train and it can be shown that time dithering on the doublets can improve the overall PSD pattern. However, only bipolar signalling can remove the spectral lines in the spectrum.
