摘　　要：音调控制电路是通过对频带宽度范围内系统的频率响应曲线的控制,来控制高低音提升衰减。通过对负反馈式音调控制电路的交流仿真分析,瞬时仿真分析以及参数仿真分析,模拟了音频范围内的高低音衰减频率特性曲线和电压增益变化曲线,验证了符合理论设计参数。对负反馈型音调控制电路进行的仿真研究,加深了电路的理解,同时也学习了EDA仿真分析技术。The tone control circuit controls the enhancement and attenuation of high and low tones by controlling the frequency response curve of the system within the bandwidth.Through the AC simula-tion analysis,instantaneous simulation analysis and parameter simulation analysis of the negative feed-back tone control circuit,the high and low attenuation frequency characteristic curve and voltage gain change curve in the audio range are simulated,which is in line with the theoretical design parameters.The simulation research on the negative feedback tone control circuit not only deepened the understand-ing of the circuit,but also learned the EDA simulation analysis technology.
