摘要
文章介绍采用DSP技术通过有效算法实现PWM脉宽调制,控制放大器输出,效率可达80%以上,为模拟功放的2倍,体积、质量为模拟功放的1/3。
Portable t lower power, lower efficie designed. Compared with esting instruments and ncy, h gher cost, large the linear amplifier, it calibrators cubage an has twice are widely used. But they are using linear amplifiers with d weight. In this paper, the PWM amplifier based on DSP is efficiency and one-third cubage.
