Question

Define the quality factor in an a.c. circuit. Why should the quality factor have high value in receiving circuits? Name the factors on which it depends.

Solution

The ratio`(omega_0L)/R`is called the quality factor or Q-factor.

`Q = (omega_0L)/R`

The quality factor has high value in receiving circuits in order to get a sharp gain for the desired channel frequency.

The quality factor depends on the values of the following:

  1. Inductance

  2. Resistance

  3. Capacitance

  Is there an error in this question or solution?
