| Abstract: | The improvement of energy resolution was studied in the digitized measurement of nuclear spectra based on the pules shape sampling and the processing of digital highpass filtering for the data of discrete digital pules.It shows that the results are good and varying with both the cutoff frequency of highpass filter and the ratio of signal to interference noise, and that there is high linearity between the input amplitudes and the output ones processed by highpass filtering. |
