Abstract
For original paper by Gordon see IEEE Trans. Signal Processing, vol.46, p.1238-44 (1998 May). With a variational method, Gordon defined the quadratures and carrier frequency different from the analytic signal (AS). This approach ignores, however, that quadratures must be bandlimited. Restriction of bandlimiting results in another solution and leads to the AS model. Gordon replies to this comment.
