摘　　要：针对FSK信号的特点,提出了基于FPGA的FKS调制器的一种实现方法--分频法,这种方法利用数字基带信号去控制可变分频器的分频比来改变输出载波频率,产生一种相位连续的FSK信号,而且原理通俗易懂,电路结构简单,容易实现。In view of FSK signal characteristic, this article advances a method-dividing frequency, which controlles the variable division ratio divider using the digital baseband signal the frequency division recently to change the outgoing carrier frequency, and produces one kind of phase continual FSK signal.The principle is very popular and easy to understand, and the circuit construction is easy and implemental.
