The Q of a tuned amplifier is 50. If the resonant frequency for the amplifier is 1000kHZ, then bandwidth is __________________?
Correct answer: D. 20 kHz
- A. 10kHz
- B. 40 kHz
- C. 30 kHz
- D. 20 kHz
Explanation
For a tuned circuit, Q = fr/BW, so BW = fr/Q = 1000 kHz/50 = 20 kHz. The resonant frequency and Q directly determine the bandwidth.
