摘要
以三输入判奇电路设计为例,通过对其输出函数表达式的形式变换,分别采用多种门电路及译码器、数据选择器等74系列器件进行电路设计,给出了7种电路实现形式,并分析了各种电路实现的优缺点。此例说明了组合逻辑电路设计的灵活性及电路实现的多样性,所采用的设计方法对其他组合逻辑电路设计具有一定的启发与指导意义。
Take the odd check circuit design as an example, the paper uses 74 series devices, the gate, decoder, multiplexer, etc, to design the odd check circuits, by changing the form of output function. Seven circuits are given respectively, and the advantages and disadvantages of the various circuit implementations are analyzed briefly. The example shows the mobility and variety of combinational logic circuits design. The method used in the paper can instruct and guide other designs of combinational logic circuits.
