| 摘 要： | “谐波分析仪”不同于目前广泛使用的“频谱分析仪”，它利用了两正弦函数相乘产生一个差频项的基本原理，最终直接观察并测量到非正弦周期信号中各个频率分量的幅值，从而验证频谱分析理论．

| Abstract: | Harmonic analyzer is different from spectroanalyzer which is widely used today. Based on the principle that the multiplication of two sine functions results in a difference frequency term, it observes and measures the amplitude of each frequency component of non-sinusoidac period signals, hereby verifies the theory of spectrum analysis. |
