摘　　要：文章对用可编程逻辑器件FPGA实现单稳态脉冲展宽电路的功能进行了研究,介绍了基于FPGA的三种单稳态脉冲展宽电路的工作原理及特点,并进行测试和仿真比较。结果表明采用时钟计数方法实现的单稳态脉冲展宽电路不仅能有效方便地对输入脉冲进行展宽和压缩,而且极大地提高了电路的可靠性和脉冲处理的精度。The function of implementing the monostable pluse-expanding circuit device is discussed in the paper. Then it concretely introduces thee processes of designing the monostable pluse-expanding circuit based on FPGA device and the respectively characteristic of the circuit, and compares them by tset and emulation.The results show that the monostable pulse-expanding circuits based on FPGA device don＇t only effectively expand or compress the inputing pulse,but also improve greatly the stability and the precision of pluse-expanding circuits.
