<p>Criou página com 'a) R = 5 Ω e Xl = 300 Ω ⇒ Q = 300/5 = 60 BW = fs/Q = 12000/60 = 200 b) fs = √ (f1.f2) Portanto: fs& = f1.f2 ⇒ f1.f2 = 144 MHz e (f2 - f1)...'</p>
<p><b>Página nova</b></p><div>a) R = 5 &Omega; e Xl = 300 &Omega; &rArr; Q = 300/5 = 60<br />
<br />
BW = fs/Q = 12000/60 = 200<br />
<br />
b) fs = &radic; (f1.f2)<br />
<br />
Portanto:<br />
<br />
fs& = f1.f2 &rArr; f1.f2 = 144 MHz<br />
<br />
e (f2 - f1) = BW<br />
<br />
(f2 - f1) = 200<br />
<br />
Se utilizarmos o critério de que, para Q > 10, a &cong; b:<br />
<br />
fs - f2 = 200/2 = 100 &rArr; f2 = 12000 - 100 &cong; 11900 Hz<br />
<br />
e<br />
<br />
fs + f2 = 100 &rArr; f1 = 12000 + 100 &cong; 12100 Hz<br />
<br />
Para comprovar, multiplicamos f1.f2 e obtemos: 143.990.000, que é aproximadamente 144.000.000 Hz!!</div>
