Abstract:
A practical workflow is presented for extracting timing and pulse-shape features from digitized detector signals and cross-validating results against an independent reference implementation. The study focuses on leading-edge timing (LET) as a baseline method and includes amplitude, baseline, rise time, and integrated charge as complementary observables. Waveforms are processed with a reproducible analysis chain that applies baseline estimation, optional digital smoothing, threshold definition, and time-pickoff via leading-edge crossing with interpolation. In parallel, an external “reference” implementation (e.g., a compact scientific- analysis code in C/C++ or a standardized DSP routine) is used to compute the same quantities under matched assumptions (sampling period, polarity, integration window, and threshold convention). Agreement is assessed through event-by-event residuals, timing-difference distributions, and stability metrics versus operating conditions (bias/shaping settings, count rate, and noise level). The workflow highlights systematic effects relevant to timing performance— time walk, baseline drift, and digitizer quantization—and provides a portable validation strategy for future DAQ developments where firmware/software algorithms must be benchmarked consistently across platforms.
