摘　　要：根据状态转换图输出属性为原态输出或次态输出,归纳和研究两类FSM电路设计方法。并从两个实例分析入手,明晰同步时序逻辑电路次态输出设计的可状态化简和寄存器输出特点,以及给出如何处理异步信号请求状态转换条件的通用方法。实际测试表明:系统具有稳定性好和结构简单等特点。It presents two types of circuit design methods for FSM based on the output properties of state transition diagram with the original state or the next state outputs. And from the two examples, state simplification and register output will be more clarified if synchronous sequential logic circuits can be designed based on next state status output. Simultaneously, it gives the general method of handling asynchronous signals requesting state transition conditions. Actual tests show that servo mechanism is of good stability and simple structure.
