AB  - This paper describes the deduction of pulse arrivaltimes from digital waveforms recorded with a multichannel data-acquisition  (DAQ)  system.  A  linear  rise  approximation  (LRA)arrival  timing  method  provides  restricted  timing  resolution  forpulses  with  nonlinear  rise.  It  reaches  1/20th  of  the  samplingperiod, if the relation between signal shaping and sampling rate isoptimized. We introduce a nonlinear rise approximation (nLRA),which  reduces  the  sampling  phase  error  (SPE)  down  to  lessthan   1/100th   of   the   sampling   period.   The   proposed   timingalgorithm uses a single free parameter that can easily be adjustedfor  various  radiation  detectors.  The  technique  permits  using  arather slow pulse shaping and low sampling rates, thus stronglyreducing power consumption and the costs of the system. A high-density  DAQ  system  integrating  over  2000  channels  inside  anOpenVPX crate is presented. A prototype has been tested in theproton  beam  at  cooler  synchrotron  (COSY)  at  Jülich  ResearchCenter (Germany).
