With the development of high-speed readout electronics, the digital pulseshape discrimination (PSD) methods have attracted the attention of moreresearchers, especially in the field of high energy physics and neutrondetection. How to choose a PSD algorithm and corresponding data acquisitionsystem (DAQ) naturally becomes a critical problem to settle down for thedetection system designers. In this paper, the relationship between theclassification performance of different PSD algorithms and digitizers' samplingproperties (including sampling rate and the effective number of bits) has beenresearched based on $\mathrm{LaBr_3}$:Ce scintillation detectors. Aself-developed integrated digitizer configured with five different ADCs and aWavePro 404HD oscilloscope were deployed to digitize the waveforms from$\mathrm{LaBr_3}$:Ce scintillators. Moreover, three PSD methods, chargecomparison method (CCM), least square for classification method (LS) andFisher's linear discriminant analysis (LDA), based on linear model were appliedto discriminate the alpha signals from the intrinsic isotope $^{227}$Ac. Withthe LS method and a 125 MSPS 14-Bit ADC, the FoM value was 1.424$\pm$0.042,which is similar to the result from LDA but 31\% better than the result of CCM.The discrimination results showed that the performances of LS and LDA are lessaffected by the sampling rate with respect to the CCM method, which reflects ina better PSD capability. The results of this paper can help the developers ofdetector systems to make a trade-off among sampling properties, desirablediscrimination results and the cost of systems.
