The input impedance is given by (6.97).

(6.97)

We know that:

(6.98)

(6.99)

(6.100)

(6.101)

Substituting (6.98) to (6.101) into (6.96), leads to (6.102),

(6.102)

where

(6.103)

and

(6.104)

, , and are defined as follows:

(6.105)

(6.106)

(6.107)

(6.108)

Therefore, the impedance Z1 and its components R1 and X1 have been parameterized to the characteristic impedance Zr1.

Figure 6.25 shows curves of the module of the parametrized as a function of fn for and different values of Q.
