Examples of Causal and Complex Wavelets?
You can always just build your own, for instance by taking the Morlet wavelet shift it to the right until, say, 99% of the area below the function is on the positive axis and then set everything on the negative axis to zero. But bear in mind that it's impossible to build a wavelet (or filter which is the same) that is causal and analytic, i.e., a filter that erases all negative frequencies, which you actually need to get that property you need (separation of phase and amplitude). However a pretty good approximation is always possible.
