Question

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

Answer 1

Answer:

The quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒr /BW.

Answer 2

Given that,

Frequency, f = 1 MHz

Bandwidth, B = 10 kHz

To find,

Quality factor

Solution,

Quality factor is defined as the ratio of frequency to the bandwidth. It is given by :

$Q=\dfrac{f}{B}\\\\Q=\dfrac{10^6}{10^4}\\\\Q=10^2=100$

So, the quality factor of the RF oscillator is 100.
