With the advent of fast high resolution Analog to Digital Converters (ADCs) and Field Programmable Gate Arrays (FPGAs), 'all digital systems' for pick-up data processing to calculate position and tune have become commonplace. The flexibility of these digital systems is very advantageous since it permits the change of position determination algorithms based on beam conditions, accelerator operation modes and measurement requirements. This contribution compares the frequently used position determination algorithms in terms of measurement variance, bias, robustness and computational complexity using simple analytical model. The analytical model is compared to the beam data to evaluate its applicability and conclusions on the optimum position estimator are derived.
