本文提出一种基于DSP 的SPWM 波形生成新方法―单元脉冲舍入法。产生的SPWM 波经过滤波后转变成的正弦波,具有 频率高、频率范围宽、波形畸变小的特点,可以用做数据通讯的载波,并且已经成功地应用在基于DSP 的软件调制解调器中。-This paper presents a DSP-based SPWM waveform to generate new methods- unit pulse rounding method. SPWM wave generated after filtering through into the sine wave, with high frequency, wide frequency range, waveform distortion of small features, can be used to do data communications carrier and has been successfully used in DSP-based software modems.
