Based on these theories, we can deduce the error diffusion with output-dependent feedback method that can control the dot-gain distortion well.

由此，可以演化出根据设备特性反馈改变簇点中少数点多少的绿噪声半调算法，使得程序的健壮性提高，对点增益现象可以很好的控制。

Additional negative feedback is provided to set loop gain to unity at the oscillation frequency, to stabilize the frequency of oscillation, and to reduce harmonic distortion.

为了使振荡频率稳定并降低谐波失真，需要加入一个在震荡频率处能够提供单位增益的负反馈路径。
