英文摘要：

For the problem of implementation of digital trapezoidal shaping algorithm in FPGA, an improved FP- GA - based structure of digital trapezoidal shaping filter was proposed. The SIMULINK simulation and FPGA - based experiments show that the improved FPGA - based trapezoidal shaping filter can adjust the trapezoid signal rise time and flat top time parameters flexibly, and can expand the measurement range of the multi - channel pulse height analyzer with different nuclear radiation detectors and signal conditioning circuit configuration.
