questions in RF Circuit Design book Опции

[Sara00]

Hello dear
if there is no problem please at first download this 2papers of RF circuit design book.

in the first page "The effect of component q on loaded q"
this paragraph shows me that the equivalent of the inductor with series resistor in parallel.
1-what the inductor in parallel shows us?(at resonant and after and befor)

in the next page(2)
how does it draw the equivalent of inductor resistor in scheme 2-16C from 2-16B?because we have only inductor q and capacity in Henry with out resonant frequency?


Thanks

For page 2 : Xp=(L/C)^0.5, and Rp=Xp*Q
