Which of the following can be used to determine the Q of a series-tuned circuit?
Pick an answer to check it.
Answer: C. The bandwidth of the circuit's frequency response
Q equals the resonant frequency divided by the bandwidth. Measuring the bandwidth of the circuit's frequency response lets you find Q; a narrower bandwidth means higher Q.
Tip: Q = f / bandwidth.
