[amp_mcq option1=”Sensitivity” option2=”Fidelity” option3=”Selectivity” option4=”None of the above” correct=”option3″]
The correct answer is C. Selectivity.
The Q of a tuned circuit is a measure of its sharpness of resonance. A high Q circuit has a narrow bandwidth and is therefore more selective than a low Q circuit.
Sensitivity is a measure of how much input signal is required to produce a desired output signal. Fidelity is a measure of how closely the output signal resembles the input signal.
Neither sensitivity nor fidelity are directly related to the Q of a tuned circuit.
