摘　　要：给出了一种新型的基于FPGA的吞脉冲小数分频器,推导了小数分频器输出频率与输入频率之间的函数关系,给出了基于MATLAB的数学仿真和基于MAX＿PLUSII的FPGA功能仿真波形。实验结果表明,输出信号频率与预置删除脉冲数之间是线性变化的。gives out a new FPGA fraction frequency divider according to swallowing pulse technique, deduce the relation of fraction divide between output frequenc y and input frequency. The mathematics imitation based on MATLAB and the FPGA fu nction imitation based on MAX_PLUS II is presented. The experiment result expres s the output frequency with prepare to place what deletion of the pulse number i s a line variety.
