摘要
OTL音频功率放大电路是电子技术课程较复杂的一个实验内容,由于目前课时又比较紧张,如何在有限的时间内,保证实验的成功,提高实验的质量,是普遍面临的一个问题。本文采用理论推导分析电路的工作原理和最佳的性能指标,再用Multisim 10.0仿真软件对理论推导进行了辅助分析,并对实验电路进行了性能仿真,最后,实际实验结果与理论推导和仿真分析结果一致。这种理论推导加仿真辅助的实验方法可以用于实验前的预习,实验中的分析,实验后的总结与提高,提高了实验的效率和效果。
It is a complicated experiment for OTL audio power amplifier in electronics courses. Due to the tight experiment class time, it is a common challenge for us to ensure success and raise the quality for the experiment. In this article, the theoretical deducing is used and the best performance of the circuit is obtained. Thereafter, the circuit simulation tool Multisim10. 0 is used for theoretical analyzing assistant and experimental circuit simulation. In the end, the real test result in lab accords with the theory and simulation. The theoretical deducing with simulation assistant method Can be used in pre-study, in actual experiment and in summarizing and improving after the experiment. It does raise the efficiency and effectiveness of the experiment.
