This paper presents a method for realizing the decimal frequency divider based on FPGA,introduces the limitation of the current frequency dividing design in brief,and a new method based on two grades' counters for implementing the decimal frequency divider is given.The principle of the design and the block diagram of the realization are also presented in this paper. Through simulated by software,this method is proved to be able to effectively implement the adjustment of the fraction of the input signal frequency.The advantages and disadvantages of this method are analyzed.The results show that this method can complete the slight adjustment of the signal frequecy,and the frequency switching time has been reduced to 2.56μs.
