摘　　要：为满足电子技术信号放大电路的实验教学设计,采用了多种信号输入音频放大器的焊接与调试项目。利用多级信号放大器静态工作点和动态各参数的设计,学习使用多用表检测各级放大电路的静态工作点,使用示波器检测动态参数和调试信号失真波形,以加强培养工程技术人员对电子产品的故障分析和处理能力。重点突出了信号通道的检测与调试方法,以便设备运维技术人员掌握故障分析和处理方法,有助于培养设备运维技术人员的故障判断能力,从而快速调试好各类设备系统使其正常运行。In order to satisfy the experimental teaching design of signal amplification circuit in electronic technology, various welding and debugging projects of signal input audio amplifier are adopted. Using the design of the static working point and the dynamic parameters of the multistage signal amplifier, learning to use the multipurpose meter to detect the static working point of the amplifier circuit at all levels, using the oscilloscope to detect the dynamic parameters and signal distortion waveform debugging. Strengthen the engineering and technical personnel to electronic products fault analysis and processing ability training. This paper focuses on the signal channel detection and debugging methods, so that equipment operation and maintenance technicians master fault analysis and processing methods. It helps cultivate the fault judgment ability of equipment operation and maintenance technicians, and quickly debug all kinds of equipment systems to make them run normally.
