Examples show that this method can decompose the imagefrequency for gradually reduced N-and IMF and the remainder.
实例表明，此方法能较好的将图像分解为频率逐渐减小的N个IMF和余项的和。

When it is realized by using the analog devices, the conventional quadrature coherent detector may result in the large imagefrequency errors.
传统的正交相干检波器由模拟器件构成，存在较大的镜频误差。

The main structure of the mixer adopts two symmetrical single-balanced mixers, with phase-shifting of the up and down path signals to eliminate the imagefrequency.
