Again, the prediction-error filter is (1, –0.4), just as before. The reason for this sameness is that the two input wavelets $b=\left({\rm {2,1}}\right)$ and $b{=(1},2{\rm {)}}$ have the same autocorrelation. Each wavelet with the same autocorrelation (regardless of whether the wavelet is minimum phase, mixed phase, or maximum phase) is associated with the same prediction-error filter.
