2、RS触发器功能Evaluationonly.CreatedwithAspose.Slidesfor.NET3.5ClientProfile5.2.0.0.Copyright2004-2011AsposePtyLtd.Evaluationonly.CreatedwithAspose.Slidesfor.NET3.5ClientProfile5.2.0.0.Copyright2004-2011AsposePtyLtd.5.1.10分析各种结构触发的翻转特点基本RS触发器：没有CP信号，Q状态由R/S直接决定；同步触发器：有CP信号控制，

3、高(低)电平期间Q状态保持，(高)低电平期间Q状态由输入端决定；主从触发器：动作分两步,CP=1(0)时主触发器接收信号，从触发器不变；CP下降沿(上升沿)到来，主触发器保持，从触发器翻转，CP=0(1)后，主从触发器都不再翻转而保持。边沿触发器：触发沿前接收输入信号，触发沿时候翻转，触发沿后封锁信号。Evaluationonly.CreatedwithAspose.Slidesfor.NET3.5ClientProfile5.2.0.0.Copyright2004-2011AsposePtyLtd.Evaluationonly.C
