In the application of above 24V fort current voltage grade control circuit, Voltage Alternating and resonant wave interference of input model for Programmable Logic Controllers must be resolved. 可编程控制器在高于24V的直流电压等级控制回路中应用时需解决输入模块的电压变换和谐波干扰等问题。
A novel method for the construction of self-dual circuits, which is essential in alternating logic, is proposed based on the original method of constructing self-dual circuits. 在传统自对偶电路实现方法的基础上,提出了一种从门级层次上构造交替逻辑结构中所必须使用的自对偶电路的新方法。
