Questions and Answers

What is the approximate bandwidth of the baseband signal mentioned in the text?

1650 kHz

45.5 kHz

10 kHz (correct)

455 kHz

What is the calculated value of Q for the given example in the text?

45.5 (correct)

165

What is the formula given in the text to calculate the Q factor of a tuned circuit?

$Q = \frac{f_c}{Bandwidth}$ (correct)

$Q = \frac{Bandwidth}{f_c}$

$Q = \sqrt{f_c \times Bandwidth}$

$Q = f_c \times Bandwidth$

Why is it easier to design a tuned circuit for the calculated Q value of 45.5?

It is a fixed and practical value of Q, making it easier to design. Signup and view all the answers
