RC 滤波参数对 PWM 方式 D/A 转换精度的影响

Effect on Conuevting Accuracy of D/A Done by Parameter of RC Filter

提出了用ＰＷＭ加ＲＣ滤波器，实现Ｄ／Ａ转换时，ＲＣ时间常数对转换精度和速度的影响，调宽脉冲是实现Ｄ／Ａ转换精度的重要途径。

The paper puts forward that RC time constant affects conuerting accuracy and conuerting velocity when we implement D/A converter by appending RC filter to PWM. And pulse widened is an important way to fulfill converting accuracy of D/A.
