In this paper, three methods to measure the efficiency of inverter have been discussed and compared. Based on the conclusion, analogmultiplication method is employed.
文中分析、比较了测量逆变器效率的三种方法后，提出采用模拟相乘方法作为硬件处理方案。

The multiplication of correlation could be implemented just by pseudo random gating sampling (analog) or data reservation control and rejection (digital).
相关处理乘法可简单地用伪随机门控采样(模拟)或伪随机控制数据保留与剔除(数字)方法实现。
