  In the preceding Comment (quant-ph/0209032) Trifonov disputes our recently
proposed uncertainty relations for a quantum particle on a circle. He states
that (i) the quantity $\Delta^2(\hat\phi)$ introduced by us representing the
uncertainty of the angle is not a proper measure of the position uncertainty
and therefore the proposed inequalities can hardly be qualified as a relevant
uncertainty relations on a circle; and that (ii) the most suitable uncertainty
relations on a circle are those based on the Gram-Robertson matrix. It is shown
by examples that both points are erroneous.
