本刊今年第3期编者建议剖析的“实用红外遥控开关”由红外线接收头和双D触发器组成如图1所示。现将对其电路进行分析和实验的过程阐述如下:根据D触发器的功能表可知,当置位端(?)、复位端(?)为低电平时,输出端Q与(?)的输出状态处于不确定状态、电 The third issue of this year editor’s analysis of the “practical infrared remote control switch” by the infrared receiver and dual D flip-flop composition shown in Figure 1. Now the circuit analysis and experiment process is described as follows: According to the D flip-flop menu shows that when the set (?), Reset (?) Is low, the output Q and State in an uncertain state, electricity
