摘要
为解决单片机功放电路设计,信号从模拟到数字再到模拟的传输以及软硬件相结合的复杂问题,提出了以红外对管为核心,辅以SS8050三极管和LM386功率放大器的红外光通信功放设计方案。通过对功放原理分析,结合音频模拟信号传输,完成了红外光通信的功放电路设计,实现了以红外对管代替复杂电路的纯硬件功放控制。该设计不仅达到了预期的音频播放效果,也为其他信号处理的教学设计提供参考。
In order to solve the problem of power amplifier circuit design,signal transmission from analog-digital-analog and hardware and software combination based on microcontroller,a design scheme of infrared communication power amplifier is proposed by using infrared tube as the core chip,SS8050 triode and LM386 power amplifier as the auxiliary chip. By analyzing the theory of power amplifier,combining audio analog signal transmission,the circuit of infrared communication power amplifier is designed. The pure hardware controlling power amplifier is implemented with infrared tube instead of the complex circuit. This design not only achieves the expected effects of audio player,but also provides an important reference for other teaching design on signal processing.
