摘要：

In this paper we present a pulse signal processing which combines the pulse amplitude and length discrimination. The introduced technique improves the signal-to-noise ratio, especially in case of low energy gamma radiation. The effectiveness of this approach is demonstrated on the discrimination of 6.3 keV X-ray and 14.4 keV gamma radiation of Co-57 and its utilization in Mossbauer spectroscopy. The presented signal analysis process can be easily implemented to other applications that are based on pulse detection, particularly to those, where the signals are very close to the noise level.
