What is resonance frequency?

Resonant frequency is the oscillation of a system at its natural or unforced resonance . Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.

What is bandwidth and its formula?

The bandwidth of a signal is defined as the difference between the upper and lower frequencies of a signal generated . As seen from the above representation, Bandwidth (B) of the signal is equal to the difference between the higher or upper-frequency (fH) and the lower frequency (fL).

What is Q factor formula?

The Q factor of the pMUT can be determined by the real part of the impedance frequency spectrum, which is defined as Q = f r/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.
