摘要
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 introduces a new method for generating SPWM waves based on DSP - ＂Partial Unit Pulses Remained＂. The generated SPWM waveform is filtered to get a sine wave, which features high frequency, wide frequency range, low distortion, and can be used in data communication as carrier. This method was successfully used in a software modern based on DSP.
