How is the quality factor related to the damping?
Underdamped systems combine oscillation at a specific frequency with a decay of the amplitude of the signal. Underdamped systems with a low quality factor (a little above Q = 1⁄2) may oscillate only once or a few times before dying out. As the quality factor increases, the relative amount of damping decreases.
How do you calculate Q factor for damping?
∆ω = ω0/Q Thus, Q factor could also be defined as the ratio of the central frequency ω0 to the bandwidth ∆ω. The main point of this write-up is to show how versatile the Q factor is in describing damped oscillations and resonance. - Q is a measure of damping.
What is quality factor formula?
Q-factor: In LCR Circuit, the ratio of resonance frequency to the difference of its neighbouring frequencies so that their corresponding current is 1/2 times of the peak value, is called Q-factor of the circuit. Formula: Q=R1CL.
What is the relation between quality factor and relaxation time of a damped oscillator?
If an oscillator has a higher value of Quality factor, it means that there is a lower rate of energy loss and hence the oscillations die out more slowly. Relaxation time is described as the time taken to reduce the amplitude of an oscillator to of its initial value.
