二阶格型滤波器可以较好的对信号进行噪声滤波，提高信噪比，误差较小，收敛速度较RSL快(The two order lattice filter can filter the signal better, improve the SNR, the error is small, and the convergence speed is faster than that of RSL)

三阶格型滤波器，较二阶误差小，收敛速度变快，并且减少了冲击情况的出现(The three order lattice filter has smaller error than the two order, faster convergence speed, and reduces the emergence of shock)

四阶格型滤波器，较二阶，三阶误差更小，收敛速度变快，50次即可迭代完成，在降噪方面有显著效果。(Four order lattice filter, compared with the two order, three order error is smaller, faster convergence speed, 50 iterations can be completed, in terms of noise reduction has a significant effect.)
