摘　　要：针对数字梯形成形算法在FPGA中的实现问题,提出了基于FPGA的数字梯形成形滤波器的改进结构。通过SIMULINK仿真和基于FPGA的实验验证,证明了改进后的基于FPGA的梯形成形滤波器能够灵活地调节梯形信号上升时间和平顶时间参数,并且扩展了在不同核辐射探测器和信号调理电路配置条件下的多道脉冲幅度分析器测量范围。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.
