摘要
开发了一种音频功率放大系统的硬件设计,该系统由前置放大电路、音调调节电路及功率放大电路3部分组成,借助Proteus仿真软件平台对电路进行仿真和性能测试分析。实验证明,仿真结果与实测结果非常接近,达到设计要求,证明这种设计方法可提高设计效率,节约成本,具有很好的可实现性。
A design of audio amplifier system was introduced in this paper. It consists of pre-amplifier circuit, tone adjust circuit and OCL power amplifier circuit. The simulation and performance analysis of circuit were realized by the Proteus software. The experimental results showed that the simulate value was close to actual value and met the requirements of practical design. It was proved that the design method is feasible and can effectively raise the design efficiency and reduce the costs.
