本文提出一个简单有效的方法,用以变换两个相位相差90°的三角形波为低畸变的正弦波。所介绍的实现这种变换的电路包括两个乘法器和一个绝对值器件。
In this paper, a simple and effective method is proposed to transform two sine waves with low distortion by two triangular waves whose phases are different by 90 °. The circuit described for implementing this transformation consists of two multipliers and one absolute value device.
