Simulation of digital trapezoidal shaping algorithm based LabVIEW

Shaping filter technique is the key technique of nuclear energy spectrum measurements, digital trapezoidal filter is the key to realize nuclear spectrometer digitizing. For the processing requirement of the nuclear signal in digital multi-channel system, this article did a study about trapezoidal shaping and filtering technique. And it has realized the simulation of this filter, discussed the impact on system performance or output caused by filter parameters. The result showed the parameters of digital trapezoidal filter can be optimized flexibly in accordance with actual signal characteristic to effectively adapt to subsequent measurements. (authors)
