    "abstract": "We compare the Pegg-Barnett (PB) formalism with the covariant phase\nobservable approach to the problem of quantum phase and show that PB-formalism\ngives essentially the same results as the canonical (covariant) phase\nobservable. We also show that PB-formalism can be extended to cover all\ncovariant phase observables including the covariant phase observable arising\nfrom the angle margin of the Husimi Q-function.",
