说明：  《新概念模拟电路》丛书包含了《晶体管》、《负反馈和运算放大器》、《运放电路的频率特性和滤波器》、《信号处理电路》以及《源电路·信号和电源》，绝大部分内容都是杨教授亲自实验或仿真总结之后才写出来的，非常有价值。
("New Concept Analog Circuit" series includes "Transistor", "Negative Feedback and Operational Amplifier", "Frequency Characteristics and Filters of Operational Amplifier Circuit", "Signal Processing Circuit" and "Source Circuit, Signal and Power", most of which are written by Professor Yang after his own experiment or simulation summary, and are very valuable.)
