在分立元件组成的包裹分拣机控制电路中,采用图1示出的无偏压双稳态触发器构成移位寄存器,具有节省电路元件和耗电省的优点。但由于无偏压双稳态触发器中管子的截止深度稍差,遇到较强的干扰时,就可能误翻转。怎样才能提高触发器的抗干扰能力,以保证包裹分拣机可靠地工作呢?我们用加负反馈 In the discrete components of the package sorter control circuit, the use of unbiased flip-flop flip-flop shown in Figure 1 to form a shift register, saving circuit components and power saving advantages. However, due to the unbiased bistable trigger tube cut-off depth slightly worse, encountered strong interference, you may mistake flip. How to improve the anti-jamming ability of the trigger to ensure that the package sorter work reliably? We use negative feedback
