What are equal-delay wavelets? Any two-length wavelet whose root is on the unit circle is both a minimum-delay and a maximum-delay wavelet. Such a two-length wavelet is called an *equal-delay wavelet. *In other words, an equal-delay wavelet is one that is both a minimum-delay and a delay wavelet. For such a wavelet, the roots of its *Z*-transform lie on the unit circle. It might be said that an equal-delay wavelet represents two wavelets in one.
