What is Q factor equation?
The Q factor of the pMUT can be determined by the real part of the impedance frequency spectrum, which is defined as Q = fr/Δf, where the resonance frequency fr is the frequency at which the real part of the impedance reaches its maximum, Δf is the width of the peak at its half height, so-called 3 dB bandwidth.
What does the Q in Q factor mean?
Q factor is a measure of the quality of a resonant (tank) circuit. A "high-Q" circuit has mostly reactive components (inductive and capacitive), with low resistance. It resonates strongly, with little damping (low loss).
What is Q factor in circuit theory?
The quality factor Q for the circuit is the electric energy stored in the circuit divided by the energy dissipated in one period. The Q of a circuit is an important quantity in certain applications, as in the case of electromagnetic waveguides and radio-frequency cavities where…
How do you calculate Q factor in oscillation?
∆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.
