What is a zero-point reverse of a wavelet? It is possible to consider wavelets with complex coefficients - that is, coefficients of the form u + iv, where u, v are real numbers and . An example is the wavelet (i, 0.5), where i is the coefficient at time index 0 and where 0.5 is the coefficient at time index 1. Another example is the wavelet (2 + i, 1–i, i), where 2 +i is the coefficient at time index 0, where 1 – i is the coefficient at time index 1, and where i is the coefficient at time index 2.
