Comments, with reply, on "A digital frequency independent phasemeter" by A. Nemat

The commenters point out that the phase-measurement scheme presented in the above-titled paper by A. Nemat (see ibid., vol.39, p.665-7, Aug. 1990) is essentially the same as that previously presented by the commenters (Proc. IEEE, vol.72, p.397-8, Mar. 1984). In fact, it is suggested that the former scheme is a special case of the latter one when the counting time interval tau is equal to the time period T/sub s/ of the signals. In reply, Nemat agrees that his scheme can be regarded as another approach to achieving the same goal. He goes on to point out some differences between his approach and that of the commenters.<
