摘要
“智能仪器”是测控专业学生的专业基础课,亦是本科课程中少有的专业综合性较强的课程;实验课在整个课程中占据重要地位。本文从智能仪器中的相敏解调的基本理论出发,对低通滤波器、移相器、开关驱动电路等子电路进行分析并设计。综合考虑实验安排、实验过程和实验报告,对该实验效果进行评估,为进一步综合实验的设计提供参考意见。
Intelligent Instrument is a key course for the students in measurement and control majoring and it’s also one of the specialized courses with highly comprehensive characteristic.Experiments play an important role in the course for students.The paper analyzed the basic theory of phase sensitive demodulation.The basic theory of phase sensitive demodulation is analyzed and different parts of the circuits such as low pass filter,phase shifter,switched-driving circuit are designed.The experimental arrangements,process and reports are evaluated to provide references for designing new experiment projects in the future.
