    "abstract": "The very old problem of extracting frequencies from time signals is addressed\nin the case of signals that are very short as compared to their intrinsic time\nscales. The solution of the problem is not only important to the classic signal\nprocessing but also helps to disqualify several common formulations of the\nquantum mechanical time-energy uncertainty principle.",
