五、触发器触发器是一种具有记忆功能的基本单元电路。所谓记忆功能,是指该电路在某一时刻的输出状态,不仅取决于当时输入信号的电平,还取决于以前电路输出的状态。也就是说,在去掉当前输入的信号后,它仍保留着电路在前一时刻的状态,这就是电路的记忆功能。本部分,首先介绍最基本的R-S触发器,包括电路的组成、逻辑符号、逻辑功能、有关的实验及应用。再介 Five, flip-flop flip-flop is a basic unit with memory function circuit. The so-called memory function, refers to the output state of the circuit at a time, not only depends on the level of the input signal at the time, but also depends on the state of the previous circuit output. In other words, after removing the current input signal, it still retains the state of the circuit at the previous moment, which is the memory function of the circuit. This section first introduces the most basic R-S flip-flop, including circuit composition, logic symbols, logic functions, related experiments and applications. Referral
