| Abstract: | The commenter states that the filters described in the above-mentioned paper by H. Rohling and W. Plagge (see ibid., vol.26, no.6, p.890-6, Nov. 1989) were described in general terms in his articles from 1977-8. The families of binary sequences with minimal or small loss-factors were described by the commenter in earlier publications (1980, 1987). Comparison of the data from these papers and from those of the authors shows that sequences with length 21 and 28 are not optimal.<> |
