Question

Relation between Quality factor, Bandwidth, and resonant frequency is _________

(a) \(Q=\frac{BW}{f_0}\)

(b) \(Q=\frac{f_0}{BW}\)

(c) Q = BW×f0

(d) \(Q=\frac{BW+f_0}{BW-f_0}\)

This question was posed to me in an interview for internship.

My question comes from Antenna Bandwidth topic in chapter Antenna Parameters of Antennas

Answer 1

Correct option is (b) \(Q=\frac{f_0}{BW}\)

Easiest explanation: Quality factor is defined as the ratio of resonant or center frequency to the bandwidth.\(Q=\frac{f_0}{BW}\)
