像基本的门电路一样,在电子计算机和其它数字设备等装置中,触发器也是应用极广泛的一种不可少的基本元件。 大家已经知道,在组合电路中,输出信号随着输入信号的消失而消失,它们没有“记忆”的功能,但是,在实际中需要具有“记忆”功能的元件。例如,两二进制数送到全加器相加,运算前后均需要寄存数码的寄存器。触发器就是一个能寄存一位二进制数码的寄存单元电路。 Like basic gate circuits, flip-flops are also an indispensable basic element in applications such as computers and other digital devices. As we all know, in the combinational circuit, the output signals disappear as the input signal disappears. They do not have the function of “memory”, but in practice, components with “memory” function are required. For example, two binary numbers sent to the full adder add, before and after the operation need to register digital registers. The flip-flop is a register cell circuit that holds a binary number.
