We look next at the minimum-delay wavelet (1, 0.5) and the corresponding maximum-delay wavelet (0.5, 1). Figure 6 shows the common-amplitude spectrum (dashed line) of these two wavelets. The amplitude spectrum is a hill-shaped curve with its peak at frequency 0. In other words, the amplitude spectrum is that of a low-pass filter. We see that the minimum-phase-lag spectrum (heavy line) and the maximum-phase-lag spectrum (medium-light line) add up to a ${4}{5}^{o}$ line (light line). Note that the two phase curves in Figure 6 are closer together than are the phase lines in Figure 5.
