I'd like to consult a question about reactance slope parameter.
I do not understant how to define the parameter.
As we know, reactance slope parameter x=ωo/2*(dX(ω)/dω) when ω=ωo.
Based on the classical microwave passive book written by Rizzi.
It can be treated as Energy stored in the resonant circuit.
In that book, they use Q-factor to interpret this parameter.
Since the sensitvity of the resonant circuit is a function of Q,
therefore Q can be written as
Q=1/2 lim [(Δω/R)/(Δω/wω]=ωo/2R*dx/dω when ω=ωo
I have no idea that why we need to multiple 1/2 in this equation.
Could someone give me a hand to answer this question?
Thanks a lot.
