Abstract
An automatic pole-zero (APZ) adjustment circuit for an ionizing radiation spectroscopy system. An output of a preamplifier is sampled to identify the decay time constant of the preamplifier output. A correction based upon the identified decay time constant is generated by a correction signal generator and applied through either an analog pole-zero adjustment network or a programmable digital shaping filter to accomplish pole-zero correction.
