AN2231 describes the technique used to discriminate various pulses and measure their subsequent rate with the use of a PSoC® device. The associated project demonstrates proper configuration for high-speed pulse processing. The result is converted into voltage and can be measured by any voltmeter.
Introduction
In X-Ray Spectrometry (also in Alfa-, Beta- or Gamma-) the term “Rate” means the average number of pulses from the detector that occur over a certain period of time. The main task is to select and count the pulses having the applicable amplitudes.
