Question

The resonant frequency of a RF oscillator is 1 MHz and its bandwidth is 10 kHz. The quality factor will be :

विकल्प

• 100

• 10

• 0.1

• 0.01

Answer 1

100

Explanation - 

Given,

Resonance frequency, f_r = 1 MHz = 1 × 10⁶ Hz

Bond with = 10 KHz

`"Quality Factor" = "Resonant frequency"/"Band with"`

`= (1 xx 10^6)/(10  "KHz") = (1 xx 10^6)/(10 xx 1000) = 100`
