Question:
The network shown below has a resonant frequency of 150 kHz and a bandwidth of 600 Hz. The Q-factor of the network is _________. (round off to nearest integer)
The network shown below has a resonant frequency of 150 kHz and a bandwidth of 600 Hz. The Q-factor of the network is _________. (round off to nearest integer)
Show Hint
The Q-factor is a measure of the selectivity of a resonant circuit. It is inversely proportional to the bandwidth.

Correct Answer: 250
Solution and Explanation
The formula for the Q-factor of a resonant circuit is given by:
\[
Q = \frac{f_0}{\Delta f}
\]
where \( f_0 \) is the resonant frequency and \( \Delta f \) is the bandwidth.
Given that: \[ f_0 = 150 \, \text{kHz}, \quad \Delta f = 600 \, \text{Hz} \] Substituting the values into the formula: \[ Q = \frac{150000}{600} = 250 \] Thus, the Q-factor of the network is \( 250 \).
Given that: \[ f_0 = 150 \, \text{kHz}, \quad \Delta f = 600 \, \text{Hz} \] Substituting the values into the formula: \[ Q = \frac{150000}{600} = 250 \] Thus, the Q-factor of the network is \( 250 \).
