Observations on the extrapolation of a band-limited signal problem

In this correspondence, the problem of extrapolating a time-truncated band-limited signal shall be considered with two objectives in mind: 1) to respond to the Sabri and Steenaart [1] correspondence relative to the author´s extrapolation method [2], and 2) to comment on the numerical difficulties which individuals have experienced when using various extrapolation procedures. In the discussion that follows, the terminology used in [2] shall be adopted.
