功率放大实验电路分析

Analysis of the Amplification Power Experimental Circuit

纵观许多高校的模拟电子技术实验指导书,在OTL功率放大电路这一基本实验中,由于某些器件选型欠妥,致使实测数据与希望值相差悬殊,影响实验效果。文章就这一问题作一点分析讨论,并确定出较适合该的实验电路的相关器件。

If you look at the experimentation i nstruction book of simulation circu its in many colleges and universities,some proplems will be found in the selection of some units i n the basic experiments of OTL amplifier circuit,which cause the big differe nce between observed data and expected data and affect experimental re-sult.The question will be put up and d iscussed in the article.
