Let be the Z-transform of a minimum-phase wavelet b. Then is the Z-transform of the inverse wavelet . For prediction distance , the head of b is and the tail is . For both the head and tail, the first coefficient is at time 0. Thus, the wavelet is given by , where gives a pure delay of time units. In terms of Z-transforms, this equation is .
