| 摘 要： | 从T触发器的逻辑功能入手,介绍了基于单边沿T触发器和双边沿T触发器的同步时序电路设计方法,并在分析异步触发条件的基础上,分别给出了基于单边沿T触发和双沿T触发器2n进制异步计数器的设计公式。在此基础上,讨论用双边沿T触发器设计异步时序电路的方法,以十二进制计数器的设计为例验证了设计的正确性。 |

| Abstract: | Starting from the logic function of the T flip-flop,this paper introduces the logic design method of synchronous sequential circuit consisting of single-edge-riggered T flip-flop and double-edge-triggered T flip-flop.This paper also analyzes asynchronous ripple condition and gives out the expressions of module-2n counters consisting of T flip-flop.Besides,it discusses the logic design of asynchronous sequential circuit based on double-edge-triggered T flip-flop,gives out a practical design example to show the design method for asynchronous module-12 counter.The design example shows that the design method presented here is effective. |
| Keywords: | Low power Double-edge-triggered flip-flop Counter Asynchronous sequential circuit Logic design |
