7. The inverse filter, when convolved with the seismic wavelet, converts the wavelet to a spike. For an input wavelet of length , the prediction-error filter contracts it to an -long wavelet, where is the prediction distance. Examine this statement with the use of two distinct convolutional models, the first based on a minimum-phase input wavelet and the second based on a mixed-phase input wavelet.
