- 验证实现JK触发器的复位功能时,各输入引脚应该如何接线? A: J=K=1,PR=CLR=1,CP任意接 B: PR=CLR=1,J,K,CP任意接 C: PR=1,CLR=0,J,K,CP任意接 D: PR=0,CLR=0,J,K,CP任意接
- 验证实现JK触发器的翻转功能时,各输入引脚应该如何接线? A: J=K=1,PR=CLR=1,CP上升沿 B: J=K=1,PR=CLR=1,CP下降沿 C: J=K=1,PR=0,CLR=1,CP上升沿 D: J=K=1,PR=1,CLR=0,CP下降沿
- PR[1]=[20,-50,15,10,180,-90],PR[2]=PR[1],PR[2,3]=PR[1,3]+50,则 PR[2]的值为( )
