在数字电路系统中,编译码器的功能是将一种数码变换成另一种数码。编译码器的输出状态是其输入变量各种组合的结果。编译码器的输出既可操作或控制系统其它部分,也可驱动显示器,实现数字、符号的显示。 编译码器通常是一种组合电路,其工作状态的改变无需依赖时序脉冲。这里介绍的译码器分为数码译码器和显示译 In digital circuitry, the function of a codec is to transform one type of digital into another. The output status of the codec is the result of various combinations of its input variables. The output of the codec can operate or control other parts of the system, but also drive the display, digital, symbolic display. Codec is usually a combination of circuit, the working state changes without having to rely on timing pulse. The decoder introduced here is divided into digital decoder and display translation
