Question

Define the quality of a factor in a ac circuit why should the quality factor have high value in receiving circuits

Answer 1

Answer:

Dear studnent,

 

quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is.Higher Q indicates a lower rate of energy loss relative to the stored energy of the oscillator; the oscillations die out more slowly.A pendulum suspended from a high-quality bearing, oscillating in air, has a high Q, while a pendulum immersed in oil has a low one.  

 

For the receiving circuits, the sensitivity must be high. So, the Q factor must be high.

 

The Q factor (quality factor) of a resonator is a measure of the strength of the damping of its oscillations, or for the relative linewidth.

 

 

The Q factor of a resonator depends on the optical frequency ν0, the fractional power loss lper round trip, and the round-trip time Trt:
