摘要
50Hz正弦信号的有功功率测量技术目前已经很成熟,但是,用传统测量方法对音频或更高频率正弦信号有功功率进行高精度测量还无能为力。文章提出采用数字信号处理技术实现无理论误差的音频正弦信号有功功率的测量。
The active power measure technology of 50Hz sin signal is already very ripe.But,the measure method with tradition is still powerless to carrying on high-accuracy measurement of active power of Audio frequency or higher frequency sin signal.In the article,the algorithm of active power measurement of no theory error with DSP is introduced.
