现代电气函授班辅导教材已全部刊出。为了配合教学,我们特组织编写了部分实验电路(包括模拟电路、数字电路两部分):并供应实验电路中所需的全部集成电路,以满足广大学员和读者的需要。由于篇幅所限,实验电路将分两期刊登出。本班要求广大学员认真动手实验制作,并选择模 Modern electric correspondence class teaching materials have been published. In order to cooperate with teaching, we have organized part of experimental circuits (including analog circuits and digital circuits) and supplied all the integrated circuits required in the experimental circuits to meet the needs of the majority of students and readers. Due to space limitations, the experimental circuit will be published in two phases. This class requires the majority of students to experiment with production, and select the model
