摘要
介绍采用一块专用的脉宽调制芯片,用一种新的方法对音频信号进行处理,并配以合适的功率输出、解调电路,减小失真、提高带宽,使其成为一个性价比较高的功率放大器。
This paper presents a kind of audio PWM power amplifier, in which the special pulse wide modulation IC SG3525 is used to complete signal processing of modulating. Chosing suitable power output and demodulation electro circuit to reduce the distortion and expand frequency band, it makes the amplifier better performance and lower cost.
