Damped OscillationsHardQuestion 31154

Question

Quality factor Q of a damped oscillator is:
  1. A
    Total energy / energy lost per cycle × 2π
  2. B
    Damping coefficient × natural frequency
  3. C
    Natural frequency / bandwidth
  4. D
    Both 1 and 3
    Correct

Correct answer

Both 1 and 3

Explanation

Q = 2π × (energy stored)/(energy dissipated per cycle) = ω₀/Δω (ratio of resonant frequency to bandwidth). Both definitions are equivalent.
