  1. The resonant frequency of an RF amplifier is 1 MHz and its bandwidth is 10 kHz. The Q-factor will be—
    1. 10
    2. 100
    3. 0.01
    4. 0.1
Correct Option: B

Given,
fr = 1MHz = 1 × 106 Hz
BW = 10 KHz = 10 × 103Hz
We know that quality factor,

Q =Resonant frequency
Bandwidth

Q =fr = 1 × 106 = 100
BW10 × 103
