| 摘 要： | 利用某些高频实验箱做高频丙类功率放大器实验时,常会出现观察不到输出信号的现象,或者得到放大器没有放大能力的结论。结合具体实验电路,利用理论知识对相应的实验现象进行分析判断后,对实验步骤做出某些改进。结果不仅解决了问题,顺利完成实验,达成实验目的,而且进一步巩固了相关的高频理论知识,收到相当好的效果。

| Abstract: | Usually only the noise waveforms of output signals is observed or the conclusion that the amplifier has no amplify ability is made when we do the third high frequency amplifier experimentation with some high frequency laboratorial box.The operation steps are improved after the experimental phenomena are analyzed based on both theorization knowledge and experiment circuits.Not only the experimental aims are achieved well,the correspondence theories of high frequency are strengthened based on the given solutions. |
