摘要
介绍了一种音频范围内功率测量的新方法．这种方法是以有效值转换电路实现模拟运算，以程序数据处理实现数字计算，同时利用了新的算法，克服了热电式、时分割式、采样计算式等方法测量音频功率的不足之处。文中定量地给出了这种功率测量方法对测量误差的影响，为音频范围功率的准确测量提供了新途径。
A new method for power measurement of audio frequencies is introduced. The scheme accomplishes analogy operation by RMS converting circuit and digital calculation by program using a particular algorithm, which can avoid the defects of thermoelectric meter, time division and sampling algorithm for power measurement of audio frequencies. The error analysis of the new method is also presented.
