| Abstract: | The design and test of a digital filter to nuclear signals based on LabVIEW were described. Three methods of digital shaping filter to nuclear signals, which include Gaussian shape filtering based on wavelet analysis technology, matched shape filtering, and trapezoidal shape filtering were achieved. To verify the performance of the filter, a digital nuclear signal generator was designed as signal source. The test results of the effect of shaping filter algorithm were studied by altering the filtering parameter. The results show that the digital filter has good performance. |
