摘要
比较了直流电源、信号发生器、频率计、毫伏表的内部电路 ,给出了一种替代上述仪器功能的多功能电子仪器的设计方法 ,分析了其性价比。
The internal circuit of D.C. power supply,the signal generator,the frequency meter and the micro_vol_tage meter were compared,then a design approach of the newly multifunctional electrical instrument which can replace the four meters above has been given. The performance cost ratio of the design has also been analyzed.
