본문내용
⑩ From table 3-8, calculate the resonance frequency, half power point frequency, and Q
Resonance frequency = is minimum = 10.49kHz
Half power point frequency = { } = ,
⑪ Is V(R) = for the resonance state? If it isn`t, why?
No, theoretically, =0 and as the resonance state. But we couldn`t observate, we just got minimum value. We think it is because there are some experimental erros from oscilloscope itself, the way that we read the frequency when it is not stable and noise, etc.
⑫ Considering V(L), V(C) for the resonance state, What is Q of this resonance circuit?
⑬ Is Q in ⑩ the same as that in ⑫? If it is, what does that mean? (Neglect the error between those values.)
In our experiment they are different. But if we neglect the error between them, so if they are same, it means Q is own property of the elements of the circuit that it isn`t depend on the frequency or voltage of the input signal.
⑭ Graph the resonance line using table 3-8.
