What does the higher value of Q-factor signify ?

a. Low Bandwidth & High frequency selection
b. High Bandwidth & Low frequency selection
c. Low bandwidth & Low frequency selection
d. Higher Bandwidth & Higher frequency selection

Correct Answer : a. Low Bandwidth & High frequency selection

Explanation :

Quality factor measures the sharpness of the resonance level. Hence, high quality factor indicates higher current & voltage magnification for parallel & series resonance respectively. Lower the bandwidth value, maximum is the range of frequency selection.
