摘要
设计了基于集成运算放大器的综合性实验系统。该系统包括正弦波、方波、三角波发生电路,电压跟随器电路,反相比例求和电路以及有源低通滤波电路。实践证明,学生通过动手操作加深了对运算放大器的理解,对信号的叠加与去噪形成了初步认识,锻炼了动手能力。
A comprehensive experimental system based on integrated operational amplifier is designed.The system includes sine wave,square wave,triangle wave generating circuits,voltage follower circuit,inverse proportional summation circuit,and active low pass filter circuit.Practice shows that students can improve their understanding of operational amplifiers and have a preliminary understanding of signal superposition and denoising,as well as improve their operation abilities.
