| Abstract: | With the help of the relation of the the group delay time with the Q-factor,Q-factor is adopted to evaluate the phase shift.this way is more clearly and easily than with phase-frequency characteristic of determing the group delay time. |

| Keywords: | Q-factor group delay time phase shift |
