the second category may be less interesting from an algorithmic point of view, since the algorithms are more time consuming than the algorithms of the first category; it has however two main advantages: it clarify in some sense the properties needed to make the computation for a given function [DELTA], and it leads to a surprising proof of some mathematical identities involving the function arctan.
Phase can be expressed as phase = arctan [imaginary(FFT)/real(FFT)] where the arctan function needs to operate over the entire range of [+ or -][pi] radians.
