What is the formula given in the text to calculate the Q factor of a tuned circuit?
What is the formula given in the text to calculate the Q factor of a tuned circuit?
- $Q = \frac{f_c}{Bandwidth}$ (correct)
- $Q = \frac{Bandwidth}{f_c}$
- $Q = \sqrt{f_c \times Bandwidth}$
- $Q = f_c \times Bandwidth$
