Digital signal processing techniques were employed to investigate the jointuse of charge division and risetime analyses for the resistive anode (RA)coupled to a microchannel plate detector (MCP). In contrast to the typicalapproach of using the relative charge at each corner of the RA, this jointapproach results in a significantly improved position resolution. Aconventional charge division analysis utilizing analog signal processingprovides a position measured resolution of 170 $\mu$m (FWHM). By using thecorrelation between risetime and position we were able to obtain a measuredresolution of 92 $\mu$m (FWHM), corresponding to an intrinsic resolution of 64$\mu$m (FMHM) for a single Z-stack MCP detector.
