How many wavelets can be generated from N dipoles? If every two-length wavelet in a group of N dipoles is distinct, there are ${2}^{N}$ possible (N + 1)-length wavelets that can be generated by taking one two-length wavelet from each dipole. Of course, if some of the two-length wavelets are not distinct, some of the (N + 1)-length wavelets will not be distinct either. In any case, all the (N + 1)-length wavelets generated in this way from one group of dipoles will have the same autocorrelation. These (N + 1)-length wavelets, so generated, are said to belong to a suite of wavelets all with the same autocorrelation.
